Rapid eye movement (REM) sleep deprivation causes learning and memory deficits. Neuropeptide S, a newly discovered neuropeptide, has been shown to regulate arousal, anxiety, and may enhance long-term memory formation and spatial memory. However, it is unknown whether neuropeptide S could improve the REM sleep deprivation-induced memory impairment. Here, we report that 72-h REM sleep deprivation in rats resulted in spatial memory impairment and reduced phosphorylation level of cAMP-response element binding protein in the hippocampus, both of which were reversed by central administration of neuropeptide S. The results suggest that neuropeptide S mitigates spatial memory impairment in rats induced by 72-h REM sleep deprivation, possibly through activating cAMP-response element binding protein phosphorylation in the hippocampus.

D008568 Memory Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.
D008569 Memory Disorders Disturbances in registering an impression, in the retention of an acquired impression, or in the recall of an impression. Memory impairments are associated with DEMENTIA; CRANIOCEREBRAL TRAUMA; ENCEPHALITIS; ALCOHOLISM (see also ALCOHOL AMNESTIC DISORDER); SCHIZOPHRENIA; and other conditions.
