Basal forebrain histaminergic transmission modulates electroencephalographic activity and emergence from isoflurane anesthesia.

abstract：BACKGROUND:Cortical acetylcholine originates in the basal forebrain and is essential for maintaining normal cognition and arousal. Morphine impairs these cholinergically mediated cortical functions. The current study tested the hypothesis that morphine decreases prefrontal cortical acetylcholine release by acting at th...
