The hippocampus contains neural representations capable of supporting declarative
memory. Hippocampal place cells are one such representation, firing in one or few locations …

The hippocampus is implicated in associative memory and spatial navigation. To investigate
how these functions are mixed in the hippocampus, we recorded from single hippocampal …

When exploring new environments animals form spatial memories that are updated with
experience and retrieved upon re-exposure to the same environment. The hippocampus is …

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 …

Distinct ensembles of hippocampal cells can be active in numerous contexts, but specific
“cognitive maps” tend to be retrieved on repeat visits to the same place. During aging, the …

Hippocampal place fields show remapping between environments that contain sufficiently
different contextual features, a phenomenon that may reflect a mechanism for episodic …

The hippocampus is the main locus of episodic memory formation and the neurons there
encode the spatial map of the environment. Hippocampal place cells represent location, but …

The hippocampus is thought to mediate episodic memory through the instantiation and
reinstatement of context-specific cognitive maps. However, recent longitudinal experiments …

Using Ca2+ imaging in freely behaving mice that repeatedly explored a familiar
environment, we tracked thousands of CA1 pyramidal cells' place fields over weeks. Place …

Hippocampal place cells selectively fire when an animal traverses a particular location and
are considered a neural substrate of spatial memory. Place cells were shown to change their …
