Readership: CIM is primarily for physicians, psychiatrists, neurologists, sleep medicine specialists, basic scientists and social scientists.

Authorship criteria: Authorship credit should be based on 1) substantial contributions to conception and design, acquisition of data, and/or analysis and interpretation of data; 2) drafting the article or revising it critically for important intellectual content; 3) final approval of the version to be published; and 4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. Every author should meet all of these four conditions. After the initial submission of a manuscript, any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. This letter must be signed by all authors of the paper. Copyright assignment must also be completed by every author. CIM does not allow multiple corresponding authors for one article. Only one author should correspond with the editorial office and readers for one article. CIM does accept notice of equal contribution for the first author when the study was clearly performed by co-first authors. Correction of authorship after publication: Science Editing does not correct authorship after publication unless a mistake has been made by the editorial staff. Authorship may be changed before publication but after submission when an authorship correction is requested by all of the authors involved with the manuscript.
