The Journal of Clinical Neurophysiology features original research articles that cover key concerns in electroencephalography and evoked potentials, clinical neurology, neurosurgery, psychiatry, and experimental research on the central nervous system. Half of each issue is devoted to topical reviews on a subject of interest to EEG specialists. This popular feature enables the editors to explore new or controversial findings in depth. Also included are practice guidelines from the American Clinical Neurophysiology Society, abstracts, book reviews, editorials, and news and announcements from the Society and the American Board of Qualification in Electroencephalography.
