Non-rem Sleep Stage Transitions Control Rem Sleep Rhythm
1423 Stage Transition Mechanism for Ultradian Rhythm—Kishi et al neurons themselves. Although further modifications of the original reciprocal interaction model, e.g., the incorporation of selfinhibitory cholinergic autoreceptors and excitatory interactions between cholinergic and non-cholinergic REM-on neurons, have been proposed over the past 30 years with new findings of synaptic details of ...
متن کاملIs the nonREM-REM sleep cycle reset by forced awakenings from REM sleep?
In selective REM sleep deprivation (SRSD), the occurrence of stage REM is repeatedly interrupted by short awakenings. Typically, the interventions aggregate in clusters resembling the REM episodes in undisturbed sleep. This salient phenomenon can easily be explained if the nonREM-REM sleep process is continued during the periods of forced wakefulness. However, earlier studies have alternatively...
متن کاملTiming of REM sleep is coupled to the circadian rhythm of body temperature in man.
Ten male subjects were studied for a total of 306 days on self-selected schedules. Four of them developed bedrest-activity cycle period lengths very different from 24 hr (mean = 36.8 hr) despite the persistence of near-24-hr oscillations in other physiologic functions, including that of body temperature (mean = 24.6 hr). The percentage of sleep time spent in REM sleep varied significantly with ...
متن کاملAstrocytic IP3/Ca2+ Signaling Modulates Theta Rhythm and REM Sleep
Rapid eye movement (REM) sleep onset is triggered by disinhibition of cholinergic neurons in the pons. During REM sleep, the brain exhibits prominent activity in the 5-8 Hz (theta) frequency range. How REM sleep onset and theta waves are regulated is poorly understood. Astrocytes, a non-neuronal cell type in the brain, respond to cholinergic signals by elevating their intracellular Ca2+ concent...
متن کاملAntidepressant suppression of non-REM sleep spindles and REM sleep impairs hippocampus-dependent learning while augmenting striatum-dependent learning.
Rapid eye movement (REM) sleep enhances hippocampus-dependent associative memory, but REM deprivation has little impact on striatum-dependent procedural learning. Antidepressant medications are known to inhibit REM sleep, but it is not well understood if antidepressant treatments impact learning and memory. We explored antidepressant REM suppression effects on learning by training animals daily...
