Historically, neuroscientists thought that … · our memories may not be as stable as we thought. A growing body of evidence suggests that they can “drift” across different populations of neurons, and this latest study has … · their findings reveal a striking double dissociation of time and experience on the hippocampal neural code: · these findings establish that representational drift occurs in mice even with highly reproducible environments and behaviour and highlight neuronal excitability as a key factor of … · here, we review recent experimental evidence for such representational drift across brain areas, as well as dissections of its functional characteristics and underlying mechanisms. · hippocampal activity is critical for spatial memory. A new study reveals that memory-related brain activity continues to shift even after learning, challenging traditional views of stable neural representations.
