The representation of distinct spaces by hippocampal place cells has been linked to
changes in their place fields (the locations in the environment where the place cells …

Hippocampal activity is critical for spatial memory. Within a fixed, familiar environment,
hippocampal codes gradually change over timescales of days to weeks—a phenomenon …

The quest to understand the memory engram has intrigued humans for centuries. Recent
technological advances, including genetic labelling, imaging, optogenetic and …

Hippocampal representations that underlie spatial memory undergo continuous refinement
following formation. Here, to track the spatial tuning of neurons dynamically during offline …

Summary Representation of the environment by hippocampal populations is known to drift
even within a familiar environment, which could reflect gradual changes in single-cell activity …

Consolidation of initially encoded hippocampal representations in the neocortex through
reactivation is crucial for long-term memory formation and is facilitated by the coordination of …

Anterior cingulate cortex (ACC) activity is important for operations that require the ability to
integrate multiple experiences over time, such as rule learning, cognitive flexibility, working …

Adult-born granule cells (abGCs) have been implicated in memory discrimination through a
neural computation known as pattern separation. Here, using in vivo Ca 2+ imaging, we …

Episodic memories are encoded by experience-activated neuronal ensembles that remain
necessary and sufficient for recall. However, the temporal evolution of memory engrams …

Recent studies show that, even in constant environments, the tuning of single neurons
changes over time in a variety of brain regions. This representational drift has been …
