Abstract: | Summary 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 average which was accompanied by an increase of K+]e from 3.0 mM to 3.31 ± 0.04 mM.Acknowledgment. I wish to express my sincere gratitude to Dr. Bure from the Institute of Physiology, Czechoslovak Academy of Sciences, for his kind help in the preparation of this article. |
