They may sanitize devices that have been cleaned (such as with soap and water). Educational objectives include 1) Reviewing current knowledge of clinical neurophysiology including: electroencephalography, evoked potentials, electromyography, nerve conduction studies, intraoperative monitoring, … Formal standards from other specialisms can also be integrated into EDF+. Orexin neurons stimulate the brain’s arousal centers. The differences in rapid eye movement (REM) sleep that are observed in the depressed patient can be related to an imbalance between monoaminergic and cholinergic systems, a difference that could therefore underlie the neurochemical basis of the disorder. European data format 'plus' (EDF+), an EDF alike standard format for the exchange of physiological data.
