Functioning of k channels during sleep

WebK-complexes have two proposed functions: [1] first, suppressing cortical arousal in response to stimuli that the sleeping brain evaluates not to signal danger, and second, aiding sleep-based memory consolidation . The K-complex was discovered in 1937 in the private laboratories of Alfred Lee Loomis. [2] Neurophysiology [ edit] WebIon channels are membrane-bound proteins that perform key functions in virtually all human cells. Such channels are critically important for the normal function of the excitable tissues of the nervous system, such as muscle and brain. Until relatively recently it was considered that dysfunction of ion channels in the nervous system would be …
