Hippocampus replay
Webb30 jan. 2024 · Thus, the proposed model may give an insight on the replay of behavioral sequences that have been observed in the hippocampus . However, further experiments revealed that sequences are also replayed in the inverse temporal order than during behavior, so-called reverse replay [ 22 , 23 ]. Webb3 maj 2012 · The hippocampus is critical for spatial learning and memory. Hippocampal neurons in awake animals exhibit place field activity that encodes current location, as well as sharp-wave ripple (SWR) activity during which representations based on past experiences are often replayed.

Webb10 feb. 2024 · As it is the case in the hippocampus (Lee and Wilson 2002), the replay of sequences takes place at a faster (5–10×), compressed rate. This increased speed of replay of the cortical sequences may have important consequences for synaptic plasticity during sleep, leading to memory consolidation, as it shortens the time interval between … Webb8 apr. 2024 · In addition, with respect to performance indicators reflecting hippocampus- (boundary-) dependent versus striatum- (intramaze cue-) dependent spatial navigation derived from relevant transfer task conditions, we expected older adults to show improved processing of hippocampus- (relative to striatum-) dependent information during …

Webb14 maj 2012 · The brain’s hippocampus plays a central role in memory storage and retrieval. The specific brain activity involved in the process, however, is poorly understood. Groups of neurons (nerve cells) often replay past experiences in split-second bursts called sharp-wave ripples (SWRs).
