Research Abstract

The electrophysiological characteristics of ORX cell in perifornical area(PFH) and lateral hypothalamus(LH) is wide action potential and biphasic wave form which are different from surrounding cells in the hypothalamus. It is appeared that they frequently firing during awake period more than sleep period. ORX cells indicated various responses against several anesthetics(sevoflurane, propofol, dexmedetomidine, ketamine, muscimol) in conscious freely moving rats. The Chenges in ORX cell activity were accordance with the changes in EEG.
