Time and experience differentially affect distinct aspects of hippocampal representational drift
Hippocampal activity is critical for spatial memory. Within a fixed, familiar environment,
hippocampal codes gradually change over timescales of days to weeks—a phenomenon …

Active experience, not time, determines within-day representational drift in dorsal CA1
Memories of past events can be recalled long after the event, indicating stability. But new
experiences are also integrated into existing memories, indicating plasticity. In the …
