Webb7 jan. 2024 · Ripples, ~80 Hz oscillations found in human HPC 8 and various neocortical (NC) areas 9–13, are of potential interest for such AMY-HPC interactions. Sharp wave-ripple complexes in HPC (SPW-ripples; ripples superimposed on ~3 Hz sharp waves), mediate widespread communication between HPC and NC during NREM sleep 14–16. Webb12 maj 2024 · Hippocampal sharp wave ripples (SPW-R) have been identified as key bio-markers of important brain functions such as memory consolidation and decision making. SPW-R detection typically relies on hand-crafted feature extraction, and laborious manual curation is often required. In this multidisciplinary study, we propose a novel, self …

Webb17 feb. 2024 · Normal hippocampal memory function relies on a variety of electrophysiological phenomena, perhaps the most notable of which are sharp wave ripples (SWRs) ( Buzsáki, 2015 ). The spectrum of SWR oscillations spans from the γ (30-80 Hz) to the ripple band (100-250 Hz). During SWRs, excitatory neurons and GABAergic … Webbcampal sharp-wave ripples cooperatively act (dialog) in a precise timing for memory consol-idation. …
Webb8 feb. 2024 · Sharp wave and ripple events are transient high-frequency field oscillations that occur spontaneously during slow-wave sleep in the brain. Norimoto et al. found that these events induced long-term depression of hippocampal synapses and may thus help to refine recently acquired memories (see the Perspective by Draguhn).
