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 … Webb16 aug. 2024 · Sharp-wave ripples (SWRs) are rapid bursts of synchronized neuronal activity elicited by the hippocampus.
