Narcolepsy-like syndrome in multiple sclerosis.

This section, IMAGES IN SLEEP MEDICINE, is intended to tap a relatively unique feature of sleep science: images that have great educational and conceptual content. These could be, for example, electroencephalograms, electromyograms, polysomnograms, portable devices, actigrams, scans including functional images, pathology specimens, brain slice preparations, fluorescent microscopy and other cutting edge techniques. The source may be human or nonhuman, but the clinical relevance should be clear. Illustrations must consist of clear and high-quality, blackand-white or color-digitized images. At this stage, videos can be submitted only for online publication. The message accompanying the picture may be a maximum of 500 words, with no more than 5 references. It is especially important not to try and make a case report out of these submissions, and detailed clinical (as contrasted to image) analysis should be avoided. The material should be submitted on the Sleep Medicine website (www.ees.elsevier.com/sleep). Images can be embedded within a text document such as Microsoft Word, a slide program such as Microsoft PowerPoint, or converted to Acrobat files. Authors should expect that the images will be available for use (with acknowledgement) to the general sleep community for teaching purposes, and so copyrighted/ patentable material should be avoided. In its final form, these images will be a freely available, searchable digital teaching image library. Comments regarding the images should be sent by e-mail to the section co-editors within a month of the publication date. These comments will be summarized and posted, if determined to be of educational content, with the original image on the journal’s web site, expected to be active for content soon. We hope this section will be enriched by the contributions of our colleagues who wish to offer stimulating opportunities for discussion and new insights in the field of sleep.
