Hierarchical nesting sleep slow oscillation
WebUnder global control of de- and hyperpolarizing slow oscillations (SOs), sleep spindles may cluster hippocampal ripples for a precisely timed transfer of local information to the neocortex. We used direct intracranial electroencephalogram recordings from human … WebMemories are often classified as hippocampus dependent or independent, and sleep has been found to facilitate both, but in different ways. In this Opinion, we explore the optimal …

WebINTRODUCTION. The fundamental biological process of sleep is governed by neurophysiological rhythms in the brain [].Sleep serves a variety of vital functions across an individual’s lifespan and is severely compromised in neurodegenerative diseases such as Parkinson’s disease (PD) and Alzheimer’s disease (AD) [].While PD was historically … Web1 de jan. de 2024 · Sleep spindles occur preferentially in the slow oscillation (SO) up-state, and can be seen as the high-frequency rhythm imposed over the SO. In the schematic, reinstatement of the ‘house in woods/pewter mug’ memory occurs during a hippocampal ripple, which is coincident with the troughs of spindles over PPA and LOC.
