Slow wave sleep induction
Webb1 apr. 2024 · One of the most characteristic electrophysiological events occurring in the sleep hippocampus is sharp wave ripple (SWR). SWRs are usually generated and observed in the hippocampus, and illustrate the most synchronous population activity patterns in the mammalian brain.
