Abstract
Averaged auditory evoked responses obtained during spontaneous wakefulness and sleep were characterized and compared with responses obtained following the administration of various monoamines in the implanted chick. Evoked responses obtained after the administration of DOPA were similar to those of spontaneous arousal, conversely, evoked responses after both NE and 5-HT were similar to responses obtained during natural slow wave sleep. The monoamine responses were associated with the characteristic EEG correlates of wakefulness (DA) or sleep (NE and 5-HT). These findings suggested that brain DA, metabolically formed from injected DOPA, is associated with a behavioral state of wakefulness, while brain NE and 5-HT are associated with a behavioral state of sleep.
