Last updated: 26 March 2008

New article type:
Techniques for Physiology

Additional help for authors

Information for Wellcome Trust- and NIH-funded authors

The Journal does not impose submission or page charges. Authors can make their papers immediately freely available online through Blackwell Publishing’s Online Open service.

SCOPE

The Journal of Physiology publishes full-length research papers and Rapid Reports of particularly important work that merits accelerated publication. Techniques for Physiology, introduced in 2008, are short papers aimed at disseminating new techniques for physiological research. Articles solicited by the Editorial Board include Perspectives, Symposium Reports and Topical Reviews, which highlight areas of special physiological interest, and Classical Perspectives describing how classic papers published in The Journal have influenced current research. Letters to the Editor and Journal Club articles are also published. All categories of papers are subjected to the same review procedure.

The Journal of Physiology does not impose page charges.
 
POLICY

Subject areas

The Journal of Physiology welcomes papers in all areas of physiology. Authors should present original work that illustrates new physiological principles or mechanisms. Papers on work at the molecular level, at the level of the cell membrane, single cells, tissues or organs and on systems physiology are all acceptable. Theoretical papers will be considered if based on experimentally derived data and if the hypothesis advanced is directly amenable to experimental testing. While emphasis is on human and mammalian physiology, work on lower vertebrate or invertebrate preparations may be suitable if it furthers the understanding of the functioning of other organisms including mammals.

Some papers may be rejected on the grounds that the subject matter is too specialized or that the contribution they make to physiology is insufficient to justify publication.

Editorial procedures

Certain members of the Editorial Board, designated Senior Editors, are responsible for assigning a paper to an appropriate Editor. It is the policy of The Journal of Physiology that each paper is independently reviewed by two people, normally the Editor and an Expert Referee; in some cases a second Expert Referee may be consulted. It is the aim of the Editorial Board that authors should receive an Editorial Report within 4 weeks of receipt of the complete manuscript in the Publications Office. Authors should note that when pairs of papers are submitted the review process may take longer. Authors should nominate two members of the Editorial Board of The Journal of Physiology to act as reviewing editors. They may also suggest suitable referees, but should not nominate referees who have been involved in any way with the submitted manuscript, or with whom they have collaborated during the past 5 years, or who are based in the same institution as the author. Authors may also identify referees who may have a conflict of interest. Authors' preferences will be taken into consideration but there is no guarantee that they will be acted upon. The final decision rests with The Journal. Any appeal against the editorial decision must be made within 2 weeks of the date of the decision letter, appeals received more than 2 weeks after the date of the decision letter cannot be considered. Manuscripts considered unsuitable for a full review, for whatever reason, will be triaged to allow authors to submit elsewhere with a minimum of delay.

Authors with manuscripts under review should not make contact regarding the manuscript with possible editors or reviewers, for example, those whose names are suggested on the submission form, as this may disrupt the review process by creating a conflict of interest for the editor or reviewer.

Editorial conflict-of-interest policy

Original manuscripts authored or co-authored by members of the Editorial Board, including the Editor-in-Chief and Deputy Editor-in-Chief, are handled by a Senior Editor, who makes all decisions about the manuscript (including choice of Editor, Expert Referees and ultimate acceptance or rejection). Original manuscripts authored or co-authored by Senior Editors are handled by the Editor-in-Chief or Deputy Editor-in-Chief of the Editorial Board, who makes all decisions about the manuscript (including choice of Editor, Expert Referees and ultimate acceptance or rejection). These entire processes are handled confidentially, and at no time do authors or co-authors who are members of the Editorial Board have access to the names of Editors or Expert Referees responsible for the review of their papers. Senior Editors and Editors do not handle or review manuscripts from their home institutions.

Overlapping material

Only in exceptional circumstances may results submitted for publication in The Journal of Physiology repeat findings already published or intended to be published by the authors elsewhere; inclusion on a website of material other than an abstract is considered as prior publication. Authors should instead refer to their previous findings in the same way as they would to work from a different group. This policy applies to results in the widest sense and not simply to figures or parts of figures. The Editorial Board emphasizes that a manuscript which is merely an expanded version of work published elsewhere is not acceptable. An exception to this policy applies in the case of an abstract that does not exceed about 400 words.

A submission must be accompanied by copies of any material, published by the authors in the last year, that overlaps the content of the manuscript. This should include preliminary notes, communications, abstracts, chapters or reviews. Please also include any ‘in press’ or submitted articles. These should be submitted as ‘Supplemental files’ in PDF format, and reference made to them in the authors’ covering letter.

Conflict of interest

Using the covering letter on the electronic manuscript submission form, authors are required to disclose any potential conflict of interest such as consultancies, financial involvement, patent ownership, etc. Where such information is not already disclosed in the manuscript, it will be held in confidence during the review process. Should the article be accepted for publication the relevant information will be given in the Acknowledgements.

Ethical standards

Authors should note that the processing of papers may be delayed if there is any doubt about their conformity with the ethical standards required by The Journal of Physiology. Because The Journal has a wide scope and readership, we always require authors to provide full information on the ethical approval process and sufficient explicit information about experimental procedures to allow non-specialist readers to appreciate the extent and need for the procedures described.

1. Research misconduct

The Editorial Board is alert to any form of research or publication misconduct including plagiarism, submission of fraudulent results/data including doctored figures, dual publication and false or incomplete attribution of authorship. It is also considered malpractice for an author to make inappropriate contact with a reviewer during the review process with the aim of influencing the outcome. The Editorial Board endorses the general principles set out in Guidelines on Good Publication Practice produced by the Committee on Publication Ethics (COPE). The Guidelines are available from the web on: www.publicationethics.org.uk. Authors should be aware that The Journal of Physiology will take action along the lines indicated in the COPE Guidelines where misconduct is suspected. Serious cases of misconduct will be referred to The Physiological Society's Publication Ethics Committee, drawn from an independent, international panel of physiologists. The authors' institutions may also be informed.

2. Animal experiments

The Editorial Board will not allow the publication of papers describing experimental procedures on living animals which may reasonably be presumed to have inflicted unnecessary pain or discomfort upon them.
To be acceptable for publication, experiments on living vertebrates or Octopus vulgaris should conform with the principles of UK legislation. Whenever appropriate, a statement should be included indicating that experiments were performed in accordance with named national legislation where this exists or, in its absence, with the requirements of the named institutional/local body concerned with the ethics of experimentation. Authors must give a full description of their anaesthetic and surgical procedures, and of peri-operative care, at every stage (including preparatory stages). Where work involves decerebrate animals the level of section must be specified; destruction of tissue rostral to the section must be included as an essential part of the technique. For anaesthesia the following details are required:

1. generic name for the anaesthetic(s);

2. dose and route used;

3. dose, route and frequency of supplementary doses, plus criteria for giving additional doses, when neuromuscular blocking agents are used.

Note that chilling is not an acceptable method for rendering cold-blooded vertebrates insentient; an anaesthetic agent must be used. Authors must provide evidence that they took adequate steps to ensure that animals did not suffer unnecessarily at any stage of an experiment, whether acute or chronic. Where relevant, the fact that animals were killed at the end of an experiment should be stated.

Authors working on isolated tissues, including primary cell cultures, must state whether the donor animal was anaesthetized or killed, and give details of the relevant procedures. Where tissues are obtained from an abattoir or similar establishment the method of killing need not be specified unless scientifically important.

Use of neuromuscular blocking agents and of nitrous oxide

In experiments involving the use of neuromuscular blocking agents authors must describe the precautions taken to ensure the adequacy of anaesthesia. They must provide sufficient detail to enable the reader to determine that no unnecessary suffering occurred. The Physiological Society has issued the following advice:

‘When neuromuscular blocking agents are used with anaesthetic agents during physiological experiments, safeguards are required to ensure that the animal does not experience unnecessary pain or distress. It is the responsibility of the person conducting the experiment to ensure that anaesthesia is adequate. Neuromuscular blocking agents should never be used without anaesthesia.

1. For any experiment using neuromuscular blocking agents it should first be established that the proposed anaesthetic regime is adequate, in the absence of these agents, to provide analgesia for any surgical procedure or noxious stimulus which is proposed. When light levels of anaesthesia are considered appropriate for experimental purposes, it should have been established that deeper levels of anaesthesia would interfere with the purpose of the experiment. All preparatory major surgery should be performed under full surgical anaesthesia. Subsequent procedures under light anaesthesia in the presence of neuromuscular blocking agents should be conducted in such a way that any residual pain from the initial surgery is blocked by local anaesthetics or analgesia and no further noxious stimuli are delivered. It should be noted that some methods of head holding using ear bars and zygomatic bars are a potential source of pain: other, atraumatic, methods of head restraint should be used in lightly anaesthetized animals.

2. During the course of each experiment in the period when neuromuscular blocking agents are used there must be a protocol for continuous or regular assessment of adequacy of anaesthesia. The appropriate methods of assessment will depend on the particular anaesthetic and the particular experiment. For example:

(a) the monitoring of changes in heart rate and blood pressure provides one of the most valuable indices of the level of anaesthesia. Neuromuscular blocking agents, in doses which do not reduce blood pressure, do not abolish autonomic cardiovascular reflexes. A preparation in which precipitate cardiovascular responses occur to minor noxious stimuli must be considered too lightly anaesthetized;

(b) the electroencephalogram can be monitored and changes in pattern with minor noxious stimuli may be a valuable guide. Thus, many experiments can be conducted while the EEG is in the unaroused state characteristic of moderate anaesthesia. However, some anaesthetics (e.g. chloralose) induce an EEG that cannot readily be interpreted, and the relation between EEG waveform and the suffering of pain is, in any case, not known. It should also be noted that changes in arterial and the administration of atropine and certain other drugs may alter the relation between the EEG and behavioural state;

(c) the state of the pupil can provide a further indication of the level of anaesthesia. Generally, under anaesthesia pupils are constricted, and dilated pupils, or pupils which react rapidly to stimuli, are indicative of inadequate anaesthesia. This is not a suitable test for experiments on the visual system when drugs have been administered which paralyse accommodation and dilate the pupils.

3. Nitrous oxide (N2O) has effective mood changing (tranquillizing) and analgesic properties and is useful because of the ease and consistency of delivery but, even at the maximum concentration feasible at normal pressures, it is not an adequate anaesthetic for surgery in cats. Caution should be used in relying upon it for maintenance, even when precautions have been taken to avoid noxious stimuli. It becomes especially important to assess the animal’s state periodically and to use supplementary agents as required.’

3. Human experiments

The Editorial Board is concerned that all work published in The Journal of Physiology should have been conducted according to the highest standards of safety and ethics. Legislation and accepted practice concerning human experimentation vary from country to country and consequently it is difficult to define absolute requirements. However, work with human subjects should conform to the standards set by the Declaration of Helsinki (last modified in 2004) (http://www.wma.net/e/policy/b3.htm), the Medical Research Council’s online guidelines MRC interim guidance on ethics of research involving human material derived from the nervous system (2003) (http://www.mrc.ac.uk/pdf-nervous_tissue_guidance.pdf), and the guidelines set out below. The objectives must be to ensure that all risks are minimized and that subjects are not injured and do not feel they have been abused as a result of participating in the study. Any definition of abuse will include excessive or unexpected pain or discomfort experienced during the experiment. Note, in the case of experiments involving minors, any risks must have been considered absent or minimal, and evidence must be presented that the experiments were performed with the understanding and consent of the legal guardian.

All manuscripts must contain statements indicating that (i) informed consent has been obtained, preferably in writing, (ii) studies conformed to the standards set by the Declaration of Helsinki, and (iii) the procedures have been approved by the local ethics committee.

1. The acceptability of procedures used will depend on the age and health of the subjects. Manuscripts should state the age, sex, health status and, where necessary, fitness of participants.

2. ‘Informed’ consent means that subjects have been told not only of the procedures and risks from the experiment but also that they are free to withdraw at any time without jeopardy. Experiments with children must have, in addition to the acquiescence of the child, the informed consent of the parent or guardian.

3. Experiments must be conducted by suitably qualified personnel with medical support where appropriate. The possible adverse physical and psychological effects of invasive procedures, painful stimuli, the stress of physical performance, sleeplessness, confinement or sensory deprivation must be borne in mind.

4. Monetary or other rewards are commonly provided in physiological studies that involve discomfort. Such rewards should not be so large as to induce subjects to participate against their better judgement. Particular care should be taken to ensure that students and junior laboratory personnel are not inadvertently coerced to participate by senior staff.

5. When drugs are to be given to a subject, their usual actions and potential side-effects must be explained verbally and, when appropriate, in writing.

6. It is the duty of the experimenter to minimize the physical risks to the subject. Such precautions will depend on the type of experiment: examples include having stops on mechanical devices, limiting the electric current provided by nerve stimulators and providing resuscitation facilities where necessary. Where procedures involve the sampling of body fluids suitable aseptic conditions must be used.

7. Procedures involving exposure to radiation should be detailed separately in the manuscript and include a statement of the dose given.

8. The identity of subjects must remain confidential; only with the written consent of the subject may his or her name be revealed.

9. Before human biopsy or post-mortem tissue is taken for study, consent must be obtained from the subject, or relatives where appropriate. This should be stated in the manuscript.

ADMINISTRATIVE PROCEDURES

Submission of manuscripts

All manuscripts must be submitted electronically using the online submission form (http://submit.jphysiol.org). Full instructions are given with the form. To avoid excessively large files, which are time consuming for both uploading by the authors and downloading for the reviewing process, no file should be larger than 5 MB (5,000K).

    Enquiries should be sent to:

    The Journal of Physiology
    Publications Office
    PO Box 502
    Cambridge
    CB1 0AL
    UK

    Tel: + 44 (0)1223 400180
    Fax: + 44 (0)1223 246858
    Email: journals{at}physoc.org
    Web: http://www.jphysiol.org

Manuscripts should be submitted initially as PDF files; numbered figures and tables should be included in the PDF file in the first instance. To facilitate the reviewing process the submitted manuscript should be formatted with the body text in 12 point Times New Roman, or a similar font, and line spacing of 1.5. Text should be left-aligned and surrounded by 3 cm margins. The formatting of text and headings will be removed during the production process and replaced with The Journal styles. Upon acceptance a Word file of the manuscript will be required. High-quality figure files will be requested if necessary. Authors wishing to have figures in colour online but black and white in print must submit both colour and black and white versions of the figures for review. They must also ensure that the figure legends apply to both versions of the figures, i.e. contain no mention of colour. As papers are now published online in manuscript form upon acceptance, it is important that figures are of a suitable quality at this stage. For details see Guidelines for preparing figures and tables. A signed Exclusive Licence Form will be required upon acceptance, together with a Colour Work Agreement Form if the manuscript contains any colour figures. Both forms are available on the online submission system. Provided these forms have been faxed to the Publications office, it is sufficient to send the originals by regular mail.

Correspondence

Following submission of a manuscript, all correspondence, up to the stage of acceptance, is dealt with by the Senior Editor whose name, address, and telephone and fax numbers are given in the acknowledgement. After acceptance all matters related to printing should be addressed to the Managing Editor at the Publications Office.

The Editors cannot accept responsibility for loss of files submitted to them. Contributors are advised to keep copies of all text and figure files during the review process.

Date of receipt

The date of receipt of each paper will be printed and is normally the date on which the manuscript is first received in the Publications Office. Papers submitted without all the information specified in these instructions will not be given editorial consideration until it has been provided; this applies especially to aspects of animal welfare/ethics. The date of receipt published will then refer to the date when the complete submission was received. If an author fails to deal with requested revisions within a reasonable time (usually one month) the date of original receipt will be replaced by the date on which the new version was received in the Publications Office.

Accelerated publication of Rapid Reports

Authors may request that their manuscript be considered as a Rapid Report for accelerated publication. Priority will be given to such papers at all stages, the Editorial Report normally being sent to authors within 4 weeks of receipt of the paper.

Rapid Reports should be complete in themselves; pairs or sequences are not allowed for papers in this category. Papers should be presented in the usual format. A Rapid Report, including figure legends, should not exceed 3500 words (about 12 double-spaced A4 pages at 12 c.p.i.; authors must indicate on the title page the number of words in the manuscript). In addition to the text allowance, up to a total of five figures/tables and no more than 30 references will be allowed. The other conditions of publication are as below.

Authors must indicate on the submission form and in the covering letter that they wish the manuscript to be considered as a Rapid Report for accelerated publication.

Letters to the Editor

Submitted letters should address serious scientific points arising out of a recent paper published in The Journal of Physiology, such as interpretation of data and methodology. The content should be objective, and there should be no references of a personal or derogatory nature to the original authors or their colleagues. Authors of published papers to which a letter may refer have a right of reply, to be published with the original letter. No new data may be introduced into a letter, but may be included in the reply. Letters and replies will be published both online and in the print version of The Journal of Physiology.

A letter should be submitted as a Word file attachment to an email addressed to mwilson{at}physoc.org It should not exceed 1000 words. The letter will be forwarded to a member of the Editorial Board for a decision. An editor may decide not to publish a letter based on lack of scientific relevance or if the subject matter of the letter is too minor to be relevant to the readership at large. If accepted, a reply is invited, The Editor reserves the right to publish the letter without a reply.

Journal Club

The Journal of Physiology encourages the submission, by graduate students, post-doctoral fellows and other training-level scientists, of short reviews of papers published within the last 3 months in The Journal. These reviews can be the result of formal laboratory journal club discussions or informal discussions among interested parties. Multiple authorship is encouraged. It is expected that senior investigators will provide assistance in the preparation of articles and it is appropriate to acknowledge such assistance. However, as the journal club is a forum for students and post-doctoral fellows, co-authorship by senior authors is discouraged. The reviews will appear under the heading ‘Journal Club’ in the table of contents.

Articles should provide a frank, honest review that is neither hyper-critical nor hyper-laudatory; articles that do not maintain the normal level of tact and respect expected of scholarly work will not be accepted for publication.

Journal Club articles will be handled by a designated Editor. Submissions will be screened by the Reviewing Editor who handled the source manuscript for accuracy and appropriateness. Submissions that necessitate more than minor revisions will not be accepted for publication.

Articles should be submitted using the online submission form (http://submit.jphysiol.org). They should consist of a brief background, a brief presentation of the data of interest and a very brief discussion of the significance of the manuscript or a specific aspect of the manuscript. Articles should be less than two pages (1500 words) and contain no more than five citations. Authors should refer to ‘Preparation of manuscripts’ below for guidance on formatting references. No abstract or figures are required and no more than one figure may be included in the article. Queries relating to a submission may be sent to journalclub{at}physoc.org

Please note that it is The Journal's policy not to publish more than one Journal Club article per year from the same author(s).

Techniques for Physiology

Techniques for Physiology is a new section in The Journal of Physiology for short papers aimed at disseminating exciting new techniques for physiological research. The papers must provide a significant advance in technology or a radical new technique that allows investigators to ask deeper questions about physiology. Papers should be relevant to current subject themes in The Journal.

Papers should be laid out in the normal format, but the Abstract should indicate in 100 words why this advance is so significant. The papers should be short (<2000 words), with no more than three figures (colour is strongly encouraged in The Journal print version). Some physiological data, showing the relevance and utility of the technique, must be shown. References will be limited to 10. Further information, such as videos, can be shown in supplementary information in the online version.

The Editorial Board may solicit submissions, but unsolicited submissions are also welcomed.

Proofs

Proofs should be corrected and returned promptly since publication is in order of receipt of corrected proofs. Excessive alterations by the authors of the accepted copy may be subject to further editorial consideration and may be charged to the authors.

Offprints

Offprints can be supplied if ordered at the same time as proofs are returned. A complimentary copy of the relevant issue of The Journal will be sent to all corresponding authors, together with a PDF file of their paper.

PREPARATION OF MANUSCRIPTS

General information

English spelling (as in The Chambers Dictionary or the Oxford English Dictionary) and terminology should be used (e.g. colour, fibre, noradrenaline). Clarity of expression and conciseness will be taken into consideration.

Arrangement of papers

    The usual format form research papers is:
    1. Title page
    2. Abstract
    3. Introduction
    4. Methods
    5. Results
    6. Discussion
    7. References
    8. Acknowledgements
    9. Tables
    10. Figures and legends

Papers deviating from the usual format can be considered for publication if there are obvious and compelling reasons for the variation. Footnotes are not acceptable.

1. Title page

The title of the paper should be as informative and interesting as possible, but authors may be asked to reduce the length if over 150 characters and spaces. The Editors will not accept a series of papers with the same main title, e.g. ‘Studies in . . . Part I’, ‘Studies in . . . Part II’. For abbreviations that are acceptable in the title see the Abbreviations section below.

A running title not exceeding 70 characters and spaces must be given for page headings.

Three key words for use in the reviewing process should be provided.

The total number of words in the paper, excluding references and figure legends, should be added to the title page.

Authors should assign their paper to one of the Table of Contents categories in the online submission form (http://submit.jphysiol.org/submission/) for the print and online Table of Contents (TOC). After publication the paper will also appear in an online collection of papers in the same TOC category. Authors can request that their paper is assigned to other online collections in the letter accompanying their submission.

Authorship

The author submitting a manuscript must ensure that all authors listed are eligible for authorship. The Editorial Board endorses the general principles set out in Guidelines on Good Publication Practice produced by the Committee on Publication Ethics (COPE; http://www.publicationethics.org.uk/guidelines). If authorship of a manuscript changes during the publication process, notification of the change, signed by the corresponding author and any authors whose names have been added to or removed from the manuscript, must be sent to the Publications Office:

The Journal of Physiology
Publications Office
PO Box 502
Cambridge
CB1 0AL
UK

The editorial process cannot proceed until this notification is received.

A statement that certain authors have contributed equally to the work may be included as a footnote on the title page.

Addresses

Authors should provide the minimum address information consistent with clarity and should ensure that authors’ affiliations are clearly indicated.

2. Abstract

This should be in one unnumbered paragraph that accurately reflects the contents of the paper and makes clear the physiological significance of the work, the problem addressed, the nature of the results, and the principal conclusions; authors are expected to conclude the summary by explaining the conceptual novelty and the broader physiological importance of their work. Results should be presented quantitatively where appropriate, together with the statistical significance, and the conclusions indicated. References may not be cited.
Since the Abstract may be used by abstracting services, a limit of 250 words is recommended. It must not exceed 5 % of the text (excluding references and figure legends), with an absolute maximum of one printed page.

3. Introduction

The Introduction should make the background and the object of the research clear, indicate the justification for the work and be understandable to the non-specialist. Reference to the authors’ previous work is desirable only if it has a direct bearing on the subject of the paper; an extensive historical review is not appropriate.

4. Methods

Methods are described once only and do not appear in the legends to figures and tables. Details should be sufficient to allow the work to be repeated by others. Authors should note that to be acceptable for publication, experiments on living vertebrates or Octopus vulgaris should conform with the principles of UK legislation.

Ethical information
Start the Methods section with a paragraph headed Ethical approval. This paragraph must contain the following information:

  1. The name of the national or local ethics committee that approved the project and the relevant regulations governing all the studies described in the paper.
  2. If experiments were conducted on humans, confirmation that informed consent was obtained, preferably in writing, that the studies conformed to the standards set by the latest revision of the Declaration of Helsinki, and that the procedures were approved by a properly constituted ethics committee, which should be named.

When describing experimental protocols the following information must be provided:

  1. The numbers of animals studied.
  2. In accord with the earlier section ‘Ethical standards’, all details concerning anaesthesia, including:
    a. Generic name of the agents, with dose and route of administration.
    b. Route and frequency of any supplemental doses.
    c. When neuromuscular blocking agents are used, the criteria used for giving supplemental doses. The Results section should give a summary of these doses.
  3. Where relevant, the method of humane killing at the end of the experiment.
  4. In studies of isolated tissues, including cell cultures, details of the methods by which these tissues were obtained, including the method of anaesthesia or killing.

Ethical information must be included for each manuscript. It is not sufficient to refer to previous publications for details, unless the paper is one of a series published in the same issue.

Where appropriate, lists of solutions, chemicals and equipment, and an explanation of data handling procedures may be given as separate headed paragraphs. The maker’s name should be given for all non-standard chemicals, apparatus and equipment. Materials known by a trade name, e.g. Perspex, have the initial letter as a capital. The Latin names as well as the common name of non-mammalian species should be given.

5. Results

Quantitative observations are often better presented graphically than in tables. Authors should ensure that their data are treated correctly, taking statistical advice if necessary. Analysis of variance (ANOVA), not t tests, should be used for multiple comparisons; parametric and non-parametric statistics should be used appropriately, and particular care should be taken over the expression of means and errors where data have been transformed onto a logarithmic scale. Standard deviations and standard errors of the means (as appropriate) should be given with not more than two significant figures; the form used, and the n value, should be stated. Tests of significance should be specified in full, e.g. Student’s paired t test. It is not usually necessary to present the individual results of a large number of repeated tests if the number of measurements is stated. Theory and inference must be clearly distinguished from what was observed, and should not be elaborated upon in this section.

6. Discussion

The Discussion, which follows the Results section, should be separate from it. The assumptions involved in making inferences from the experimental results should be stated. The Discussion should not merely recapitulate the results. Authors should provide a succinct conclusion to their work and are encouraged to conclude the Discussion by expressing an opinion on the relevance of the results in the context of work cited in the paper.

In appropriate circumstances an Appendix or a Theory section may be accepted where, for example, it is necessary to derive mathematical results required in the paper.

7. References

The paper should conclude with a list of the papers and books cited in the text. Authors should avoid an excessive number of references. Normally about 50 should be adequate (a maximum of 30 references for Rapid Reports is strictly adhered to). The order of references is strictly alphabetical, regardless of chronology. The format for references to papers and books, and to chapters in books, is as follows:

DOIs for articles in press

Many journals now publish articles online ahead of print. This initial posting to the web qualifies as publication and the citation of such articles should include the DOI (digital object identifier) if the article's full publication details have not yet been assigned:

Lipp P, Egger M & Niggli E (2002). Spatial characteristics of sarcoplasmic reticulum Ca2+ release events triggered by L-type Ca2+ current and Na+ current in guinea-pig cardiac myocytes. J Physiol; DOI: 10.1113/jphysiol.2001.013382.

In the text, references should be made by giving the author and the year of publication in parentheses, e.g. (Lamb, 1986), except when the author’s name is part of the sentence, e.g. ‘Lamb (1986) showed that . . . ’. Where several references are given together they are in chronological order, separated by semicolons.

When a paper written by two authors is cited, both names are given; for three or more authors only the first name is given, followed by ‘et al.’. Unpublished material may be referred to sparingly in the text, by giving the authors’ initials and names followed by ‘unpublished observations’ or ‘personal communication’; such citations should not appear in the list of references. References cited as being ‘in press’ must have been accepted for publication, and the name of the journal or publisher included in the reference list.

8. Acknowledgements

Acknowledgements should be the minimum consistent with courtesy. The wording of acknowledgements of scientific assistance or advice must have been seen and approved by the persons concerned. Authors must indicate the source of their funding.

9. Tables

Tables should be used sparingly. They should be referred to in the text by arabic numerals, e.g. Table 3. Each table should have its own self-explanatory title. The same information should not be presented in both tabular and graphical forms. Tables should be included in the main text file and should not be submitted as separate files. Guidelines for preparing figures and tables.

10. Figures and legends

Each figure should be given a title and be accompanied by a legend that makes it comprehensible without reference to the text, although undue repetition should be avoided. For detailed instructions for preparation of figures see Guidelines for preparing figures and tables.

Authors may submit coloured illustrations whenever they enhance the scientific value of the paper. Colour figures online only are free, but there is a charge for printing figures in colour. Upon submission of a manuscript, authors should download the Colour Agreement Form (http://www.blackwellpublishing.com/pdf/SN_Upw2000_F_CoW.pdf), which gives information on the cost of colour reproduction. Authors wishing to have figures in colour online but black and white in print must submit both colour and black and white versions of the figures for review. They must also ensure that the figure legends apply to both versions of the figures, i.e. contain no mention of colour. Upon acceptance, only the colour versions of figures that are to be colour online only should be included with the manuscript going to press. Enquiries should be addressed to the Publications Office (journals{at}physoc.org).

Where figures from previous publications are used (even if these have been redrawn), it is the author’s responsibility to obtain permission from the original journal and to include these with the submission.

Authors are encouraged to provide a figure for possible use on the cover although there is no guarantee that it will be selected. It need not necessarily appear in the paper but should be related to it. The figure must not have appeared or been submitted elsewhere.

Supplemental material

The Journal of Physiology gives authors the opportunity to submit data files that are inappropriate or impractical to include in the printed version for publication online only as separate supplemental material. These data may substantially enhance the importance of the research and be of benefit to readers, but should not be essential for the understanding of the paper, i.e. the manuscript must be able to stand alone in print and online without the data. Authors are encouraged to include data such as videos, 3-D structures/images and any other supplemental data too large for print publication.

All supplemental material must be submitted with the original manuscript. Figure legends should follow their corresponding figure. Please put all supplemental material into a single file if possible, but if the supplemental file sizes exceed 10 MB in total please contact the Publications Office (journals{at}physoc.org).

Links to web sites may be included in manuscripts, but these links must terminate on a permanent data repository, such as those of the host platforms used by The Journal. Links to private author's web pages/sites are not permitted.

Abbreviations

Authors should avoid abbreviations unless they are easily understood and help in reading the paper. Abbreviations should be defined when first introduced and are normally printed in upper-case letters without stops (a list of preferred abbreviations is available to download here [PDF]).

Symbols, units and mathematical notation

Recommended mathematical symbols and ways of printing them are given in Quantities, Units, and Symbols (1975), published by the Royal Society, London; this also includes a full discussion of the use of units.

The SI system of units and index notation should be used, e.g. ml s-1 rather than ml/s. Guidance for the use of SI units and conventions for the typeface of symbols can also be found at http://physics.nist.gov/cuu/Units/index.html

Certain traditional units that are still in common usage are also acceptable, for example:

      length, Å (SI unit nm)
      pressure, mmHg, Torr (SI unit kPa)
      radioactivity, Ci = Curie (SI unit Bq)
      O2 uptake and CO2 elimination, l min-1 (SI unit mol s-1).

Authors should ensure that consistency is maintained throughout the manuscript, including illustrations and tables.

Chemical and biological nomenclature

In general, the conventions in chemical nomenclature adopted by the Biochemical Society should be followed. These are described in the Biochemical Journal Instructions to Authors available online from www.BiochemJ.org

Names of species and genera should be in italics. Names of muscles, bones etc. should be in roman type (i.e. not in italics).
