Hierarchical nesting sleep slow oscillation

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 …
