Large-scale recordings of neural activity over days and weeks have revealed that neural
representations of familiar tasks, precepts and actions continually evolve without obvious …

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

Recent studies have shown that neuronal representations gradually change over time
despite no changes in the stimulus, environment, or behavior. However, such …

The brain can represent behaviorally relevant information through the firing of individual
neurons as well as the coordinated firing of ensembles of neurons. Neurons in the …

Fascinating phenomena such as landmark vector cells and splitter cells are frequently
discovered in the hippocampus. Without a unifying principle, each experiment seemingly …

As animals explore an environment, the hippocampus is thought to automatically form and
maintain a place code by combining sensory and self-motion signals. Instead, we observed …

There has been considerable research showing populations of neurons encoding for
different aspects of space in the brain. Recently, several studies using two-photon calcium …

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 …

The medial entorhinal cortex (MEC) creates a map of local space, based on the firing
patterns of grid, head-direction (HD), border, and object-vector (OV) cells. How these cell …

Hippocampal subfield CA3 is thought to stably store memories in assemblies of recurrently
connected cells functioning as a collective. However, the collective hippocampal coding …
