چکیده

In the present study nicotine (0.1 mg/kg, s.c.) increased discharge rate of putative dorsal raphe (DRN) serotonergic neurons of behaving rats during REM sleep (362.61%), without any significant change during waking and non-REM sleep. Since serotonergic DRN neurons gate PGO onset, these results suggest that nicotine-induced suppression of PGO spikes during REM sleep previously reported is achieved through stimulation of dorsal raphe serotonergic cells.

Role and origin of the GABAergic innervation of dorsal raphe serotonergic neurons.

Extracellular electrophysiological recordings in freely moving cats have shown that serotonergic neurons from the dorsal raphe nucleus (DRN) fire tonically during wakefulness, decrease their activity during slow wave sleep (SWS), and are nearly quiescent during paradoxical sleep (PS). The mechanisms at the origin of the modulation of activity of these neurons are still unknown. Here, we show in...

Activity of dorsal raphe cells across the sleep-waking cycle and during cataplexy in narcoleptic dogs.

Cataplexy, a symptom associated with narcolepsy, represents a unique dissociation of behavioural states. During cataplectic attacks, awareness of the environment is maintained, as in waking, but muscle tone is lost, as in REM sleep. We have previously reported that, in the narcoleptic dog, noradrenergic cells of the locus coeruleus cease discharge during cataplexy. In the current study, we repo...

Serotonergic neurons in the caudal raphe nuclei discharge in association with activity of masticatory muscles.

There is a dense serotonergic projection from nucleus raphe pallidus and nucleus raphe obscurus to the trigeminal motors nucleus and serotonin exerts a strong facilitatory action on the trigeminal motoneurons. Some serotonergic neurons in these caudal raphe nuclei increase their discharged during feeding. The objective of the present study was to investigate the possibility that the activity of...

Serotonergic (5-HT) neurons of the dorsal raphe nucleus (DRN) and cholinergic neurons in the adjacent laterodorsal

Serotonergic (5-HT) neurons of the dorsal raphe nucleus (DRN) and cholinergic neurons in the adjacent laterodorsal (LDT) and pedunculopontine tegmental nuclei (PPT) have together been implicated in the regulation and production of REM sleep (reviewed in McCarley et al., 1995; Jones, 1993). Several lines of evidence indicate that the activity of cholinergic neurons in the PPT is involved in the ...

Interleukin-1 inhibits firing of serotonergic neurons in the dorsal raphe nucleus and enhances GABAergic inhibitory post-synaptic potentials.

In vitro electrophysiological data suggest that interleukin-1 may promote non-rapid eye movement sleep by inhibiting spontaneous firing of wake-active serotonergic neurons in the dorsal raphe nucleus (DRN). Interleukin-1 enhances GABA inhibitory effects. DRN neurons are under an inhibitory GABAergic control. This study aimed to test the hypothesis that interleukin-1 inhibits DRN serotonergic ne...
