WebHistamine neurons are active during waking and largely inactive during sleep, with minimal activity during rapid-eye movement (REM) sleep. Caffeine, the most widely used stimulant, causes a significant increase of sleep onset latency in rats and WebAlthough the TMN inhibits VLPO neurons, histamine does not affect VLPO activity. However, the TMN also contains GABA, galanin, and endomorphin, all of which may be inhibitory to VLPO neurons. Interestingly, serotoninergic projections from the raphe nuclei have different effects on different VLPO neurons [ 8 ].
