Sharp wave ripple とは
Webb15 mars 2024 · Sharp-wave ripples (SWRs) are spontaneous neuronal population events that occur in the hippocampus during sleep and quiet restfulness, and are thought to play a critical role in the consolidation of episodic memory. SWRs occur at a rate of 30–200 events per minute. Their overall abundance may, however, be reduced with aging and … Webb11 aug. 2024 · SPW-Rs are composed of a sharp wave, arising from neurons in the CA3 region of the hippocampus, that brings about a fast but localized network oscillation — …

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). Webb15 jan. 2024 · Sharp waves co-occur with ripples near the cell layer 11, 22. For the detection of ripples, LFP signals were bandpass-filtered at 150–250 Hz and the root-mean-square power was calculated in the ...

Sharp wave-ripple complexes (SWRs) are brief (50–100 ms) events of elevated and synchronized network activity originating in the CA3 region of the mammalian hippocampus. They occur during periods of awake rest and slow-wave sleep ( Buzsáki, 1986, 2015) and have been shown to be critically involved in the process of …
