1 Ιουν 2017 · We propose that REMs and NREMs both contribute to memory consolidation in the healthy brain under normal circumstances. Memory consolidation, a process which stabilizes recently acquired information into long-term storage, is thought to be optimized during sleep.
Historically, there have been many attempts to tie human REM sleep to memory (e.g., Crick & Mitchison 1983, Winson 1985, Paller & Voss 2004), and diverse ideas about its role in consolidation are still debated. Here we emphasize the better understood role of non-REM (NREM) sleep.
Although recent evidence indicates that non-rapid-eye movement sleep (NREMs) is directly involved in memory consolidation, the role of rapid-eye movement sleep (REMs) in this process has remained controversial due to the extreme difficulty in experimentally isolating neural activity during REMs.
Specifically, this review outlines the historical origins of the discovery of REM sleep, the diversity of REM sleep expression across and within species, the potential functions of REM sleep (e.g., memory consolidation), the neural circuits that control REM sleep, and how dysfunction of REM sleep mechanisms underlie debilitating sleep disorders ...
30 Σεπ 2004 · Such findings suggest that REM sleep plays an active role in memory consolidation and that posttraining increases reflect a homeostatic response to the increased demands for REM-dependent consolidation.
9 Μαΐ 2024 · The general consensus today is that memory consolidation – the process of preserving key memories and discarding excessive information – takes place during both the non-rapid eye movement (NREM) and rapid eye movement (REM) stages of your sleep cycle.
4 Ιαν 2010 · Rapid eye movement (REM) sleep is characterized by a local upregulation of plasticity-related immediate early genes in the presence of high cholinergic activity and reduced...
