New research shows that our brain’s internal map rewrites itself every time we navigate a familiar environment. Within a fixed, familiar environment, hippocampal codes gradually change over timescales of days to weeks—a … The study reveals that hippocampal activity plays an … A growing body of evidence suggests that they can “drift” across different populations of neurons, and this latest study has … We tested this hypothesis by fitting a network model … · to test this hypothesis, we longitudinally recorded large populations of hippocampal neurons in mice while they repeatedly visited a familiar linear track over weeks. Demonstrate that associative learning induces changes of the active neuronal ensemble in mouse visual cortex. · hippocampal activity is critical for spatial memory. · in the hippocampus, spatial representations are known to remain stable, but have also been shown to drift over long periods of time. · our memories may not be as stable as we thought. Within a fixed, familiar environment, hippocampal codes gradually change over timescales of days to weeks-a … · representational drift (rd) should therefore be an expected and inevitable consequence of ongoing memory storage. Even when mice experienced identical virtual mazes with … · in conclusion, heightened reward expectation improves memory encoding and retrieval by maintaining reliable place fields that are gradually reinstated across days, thereby … We hypothesized that experience, more than …
