Disruption of awake sharp-wave ripples does not affect memorization of locations in repeated-acquisition spatial memory tasks
L Deceuninck, F Kloosterman - Elife, 2024 - elifesciences.org
Storing and accessing memories is required to successfully perform day-to-day tasks, for
example for engaging in a meaningful conversation. Previous studies in both rodents and …

The role of replay and theta sequences in mediating hippocampal‐prefrontal interactions for memory and cognition
Sequential activity is seen in the hippocampus during multiple network patterns, prominently
as replay activity during both awake and sleep sharp‐wave ripples (SWRs), and as theta …

Memory replay in the hippocampus
The hippocampus is required for the encoding, consolidation, and retrieval of episodic
memories, but the neural mechanisms underlying these processes are still not well …

Rewarded outcomes enhance reactivation of experience in the hippocampus
Remembering experiences that lead to reward is essential for survival. The hippocampus is
required for forming and storing memories of events and places, but the mechanisms that …

[HTML][HTML] Selection of experience for memory by hippocampal sharp wave ripples
A general wisdom is that experiences need to be tagged during learning for further
consolidation. However, brain mechanisms that select experiences for lasting memory are …

Distinct hippocampal-cortical memory representations for experiences associated with movement versus immobility
While ongoing experience proceeds continuously, memories of past experience are often
recalled as episodes with defined beginnings and ends. The neural mechanisms that lead to …
