Hippocampal activity during memory recall predicts a transient increase in the ratio between neocortical glutamate and GABA, thereby allowing otherwise dormant memories to be released.

A theory of memory consolidation illustrates the benefits of communication between short- and long-term memory systems to prioritize the storage of reliable memories.

A new magnetic resonance brain imaging measure reveals that variations in people’s ability to recall their past experiences may be related to the speed at which electrical signals travel along axons in the parahippocampal cingulum bundle.

Neural representations of both general event schemas and story-specific details predict memory performance in narrative recall, with distinct brain networks tracking schematic information during perception versus retrieval.

Human intracranial electroencephalography recordings across 177 participants and four diverse episodic memory experiments demonstrate how the anterior insula node of the salience network orchestrates dynamics of large-scale brain networks.

Conditional knockout of the small GTPase Cdc42 in excitatory neurons of the mouse forebrain leads to impaired long-term synaptic plasticity and impaired retrieval of remote memory.

Sleep plays a critical role in the selectivity of memory by promoting the retention of important memories at the expense of less relevant ones.

Changes in the interpretation of specific scenes in a narrative trigger corresponding updates in the neural patterns evoked by those scenes in the default mode network.

Intentionally preventing the retrieval of an unwanted memory hinders future attempts to reactivate the memory’s neural representation and causes a reduction in the vividness with which it can be recalled.

Activity-dependent genetic labeling during behavioral learning shows Fragile-X syndrome model mice exhibit impaired hippocampal engram reactivation, and that enriched environment experience improves fear memory retrieval by enhancing engram reactivation efficacy.
