Preoptic area neurons and the homeostatic regulation of rapid eye movement sleep.
The median preoptic nucleus (MnPN) and the ventral lateral preoptic area (vlPOA) of the hypothalamus express sleep-related Fos immunoreactivity, and a subset of Fos-immunoreactive neurons (IRNs) in these nuclei contain glutamic acid decarboxylase (GAD), a marker of GABAergic cells. We recently showed that the numbers of Fos-positive (Fos+) and Fos+ GAD-IRNs in both the MnPN and the vlPOA are po...
متن کاملHomeostatic regulation of sleep: a role for preoptic area neurons.
The median preoptic nucleus (MnPN) and the ventrolateral preoptic area (vlPOA) contain putative sleep-regulatory neurons that exhibit elevated discharge rates during sleep compared with waking. Expression of c-Fos protein immunoreactivity (IR) in GABAergic neurons in the MnPN and the vlPOA is high in spontaneously sleeping rats and in rats undergoing recovery sleep after sleep deprivation. Howe...
متن کاملRAPID EYE MOVEMENT SLEEP DEPRIVATION INDUCES ACETYLCHOLINESTERASE A CTIVITY IN THE PREOPTIC AREA OF THE RAT BRAIN
Acetylcholinesterase (AchE) is a large glycoprotein that, aside from its known cholinolytic activity, co-exists with other transmitter systems and possesses other functions. In the present study, the effects of short-term rapid-eye-movement sleep deprivation (REM-SD) on AchE activity in the anterior hypothalamic area have been investigated. Using the flower-pot method, adult male albino ra...

متن کاملRapid Eye Movement Sleep
• Rapid eye movement (REM) sleep was first identified by its most obvious feature: rapid eye movements occurring during sleep. In most adult mammals the electroencephalogram (EEG) of the neocortex is low in voltage during REM sleep. The hippocampus exhibits regular high-voltage theta waves throughout REM sleep. • The key brain structure for generating REM sleep is the brainstem, particularly th...
