WebbCoupling of sleep spindles with cortical slow waves and hippocampus sharp-waves ripples is crucial for sleep-related memory consolidation. Recent literature evidenced that nasal respiration modulates neural activity in large-scale brain networks. In the rodent, this respiratory drive strongly varies according to vigilance states. Particularly, during sleep, … Webb26 maj 2016 · Perceptual memory needs slow-wave sleep We know little about the mechanisms by which the brain consolidates nondeclarative (perceptual) memories. In a series of behavioral, optogenetic, and electrophysiological experiments, Miyamoto et al. show that coordinated neuronal information flow during sleep is required for perceptual … Webbslow-wave sleep (SWS). It is interesting that SWS declines across the life span, but little research has examined whether sleep-dependent memory consolidation occurs in older adults. smalley linear spring

Webb9 mars 2012 · Whereas spindles occur during both light and deep sleep, slow oscillations are restricted to deep sleep, raising the possibility of greater consolidation-related spindle involvement during deep sleep. We assessed declarative memory retention over an interval containing a nap and determined spindle density for light and deep sleep separately. WebbThe discovery of experience-dependent brain reactivation during both slow-wave (SW) and rapid eye-movement (REM) sleep led to the notion that the consolidation of recently …
