 Instruction for Authors

1. General Guidelines
Annals of Clinical Neurophysiology (ACN) is the official journal of The Korean Society of Clinical Neurophysiology, published twice a year on January 31 and July 31 in English. ACN (formerly Korean Journal of Clinical Neurophysiology) was launched in 1999, and publishes scientific and creative research papers in clinical neuroscience and clinical neurophysiology supporting all of the academic fields of clinical neurology. Manuscripts submitted to ACN should be prepared in accordance with the following instructions. ACN follows the Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication (http://www.icmje.org/urm_main.html), commonly known as the Vancouver style, except where described otherwise below.

2. Types of Manuscript
This journal publishes full-length original papers, case reports, letters to the editor, invited reviews, images in clinical neurophysiology, and other articles commissioned by editorial board.

3. Research and publication ethics
This journal adheres to the research ethics guidelines of The Korean Society of Clinical Neurophysiology and also to the ethical guidelines for research and publication described in “Good Publication Practice Guidelines for Medical Journals” (http://kamje.or.kr/) and “Guidelines on Good Publication” (http://publicationethics.org/files/u7141/1999pdf13.pdf). The editor-in-chief has the right to reject a manuscript if research misconduct is suspected. When violation of the publication ethics related to a paper published in this journal is detected, the authors will be announced in this journal and their institutes will be informed, and there will also be penalties for the authors.

3-1. Conflicts of Interest
The corresponding author must inform the editor-in-chief of any potential conflicts of interest that could have influenced how the authors have interpreted the data. Examples of potential conflicts of interest are financial support from or connections to pharmaceutical companies, political pressure from interest groups, and academic-related issues. In particular, all sources of funding applicable to the study should be stated explicitly.

3-2. Authorship
Authorship credit should be based on (1) substantial contributions to the study conception and design, acquisition of data, or analysis and interpretation of data; (2) drafting the article or revising it critically for important intellectual content; and (3) final approval of the version to be published. All of the listed authors should meet these three conditions. The corresponding author should (1) be responsible for all communications with this journal from submission to publication, (2) keep co-authors informed and involved during the review process, and (3) correspond with members of the scientific community after the manuscript has been published.

3-3. Redundant Publication and Plagiarism
A submitted manuscript must not be associated with any type of research misconduct, including fabrication, falsification, or plagiarism with intent to deceive by the authors. The cover letter to the editor-in-chief must declare that a submitted manuscript has not been published nor is under simultaneous consideration for publication elsewhere in whole or in part in any language, except in the form of an abstract. The cover letter must also state if the manuscript contains any portion that may be regarded as redundant or duplicate information, defined as a paper, data, tables, or figures that overlap substantially with already published information.

3-4. Research Involving Humans and Animals
Research involving human subjects must comply with the principles of the Declaration of Helsinki (1964). Articles describing research involving humans and animals must state in the Materials and Methods that the work was approved by the applicable institutional ethics committee or review board. The manuscript must also state that informed consent was obtained from the subjects, where applicable.

4. Peer Review Process
All submitted manuscripts will be initially evaluated by more than two experts in accordance with the review and revision guidelines of The Korean Society of Clinical Neurophysiology. The acceptance criteria for all papers are based on the quality and originality of the research and its clinical and scientific significance. An initial decision will normally be made within 4 weeks of the receipt of a manuscript, and the reviewers’ comments will be sent to the corresponding authors. Revised manuscripts must be submitted by the corresponding author. The corresponding author must indicate the alterations that have been made in response to the reviewers’ comments on an item-by-item basis. Failure to resubmit the revised manuscript within 8 weeks of the editorial decision will be regarded as a withdrawal.

5. Review and Publication Fee
All manuscripts except articles commissioned by the editorial board may be charged a prescribed review fee and a publication fee. The costs of special printing requirements and publishing extra issues will be charged to the authors.

6. Copyright
All published papers become the permanent property of The Korean Society of Clinical Neurophysiology, and must not be published elsewhere without written permission. A copyright transfer form should be submitted to the editorial office through electronic submission system (http://submit.e-acn.org) upon acceptance.

Although there is no set limit for the length of original articles, it is highly recommended that they be no longer than 4000 words excluding the Abstract, tables, figure legends, and references. In the Introduction, state the purpose of the research in a concise and clear way, and only include details regarding the background that are related to the purpose. In the Materials and Methods, describe the materials (or subjects) and the methods in detail. The sources of the each apparatus or reagent used should be provided in detail: name of the company and its city, (state, for US-based companies), and country location.
