Clinical Neurophysiology: Clinical neurophysiology is a medical specialty that studies the central and peripheral nervous systems through the recording of bioelectrical activity, whether spontaneous or stimulated. It encompasses both research regarding the pathophysiology along with clinical methods used to diagnose diseases involving both central and peripheral nervous systems. Clinical neurophysiological procedures commonly used in diagnosing and treating neurological disorders include EEG, MEG, EMG, evoked potentials, polysomnography, epilepsy monitoring, intraoperative monitoring, movement monitoring, and autonomic nervous system testing.
