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.

Web3 de jan. de 2024 · Main Text. Hierarchical cross-frequency phase-amplitude coupling (PAC) of neuronal oscillations, in which the phase of slower oscillations modulates the amplitude of faster ones, has been proposed as a general mechanism supporting the encoding, storage, and retrieval of information (Fell and Axmacher, 2011).During slow … WebThe systems consolidation of memory during slow-wave sleep (SWS) is thought to rely on a dialogue between hippocampus and neocortex that is regulated by an interaction … churches in millvale pa

Web10 de fev. de 2024 · NREM oscillatory activity is characterized by the neocortical slow oscillation (SO; <1 Hz), the thalamic sleep spindle (~12–15 Hz) and the hippocampal ripple (>80 Hz). The intricate interaction of SOs, spindles and ripples constitutes a set of hierarchically nested oscillations, which provides the fine-tuned temporal and spatial … Web10 de jun. de 2024 · Spindles and slow oscillations (SOs) both appear to play an important role in memory consolidation. Spindle and SO “nesting,” or the temporal overlap between the two events, is believed to modulate consolidation. However, the neurophysiological processes modified by nesting remain poorly understood. We thus recorded activity … Web12 de set. de 2024 · Slow oscillations and sleep spindles are hallmarks of the EEG during slow-wave sleep (SWS). Both oscillatory events, especially when co-occurring in the constellation of spindles nesting in the slow oscillation upstate, are considered to support memory formation and underlying synaptic plasticity.
