Arousal-induced increase of cortical [K+] in unrestrained rats.

H Korytová.   

Abstract

Changes of extracellular concentration of brain potassium [K+]e were studied in lightly anesthetized unrestrained rats with ion-selective K+-microelectrodes introduced into the cerebral cortex with a head-mounted microdrive system. Nociceptive stimuli elicited EEG arousal lasting for 47 sec on the averag which was accompained by an increase of [K+]e from 3.0 mM to 3.31 +/- 0.04 mM.
