A new review explores how episodic memories are formed, stored, and reshaped over time, revealing why our recollections of past events often change.

In a recent study published in the journal Nature Communications, researchers investigated whether post-encoding ripples improve emotional memory through amygdala-hippocampal memory restoration or ...

A study from the University of East Anglia is helping scientists better understand how our brains remember past events—and how those memories can change over time.

New research provides evidence that electric fields shared among neurons via 'ephaptic coupling' provide the coordination necessary to assemble the multi-region neural ensembles ('engrams') that ...

Compelling new research, published in the journal Proceedings of the National Academy of Sciences, is suggesting neuronal activity in the hippocampus prior to the delivery of new information can ...

Despite a century of research, memory encoding in the brain has remained mysterious. Neuronal synaptic connection strengths are involved, but synaptic components are short-lived while memories last ...

On theoretical grounds, the architecture of CA3 circuits seems to be well adapted for the rapid storage and retrieval of associative memories. This is thought to require plastic changes in the ...

This important work significantly advances our understanding of the role of human hippocampal theta oscillations in memory encoding and retrieval. The evidence supporting the conclusions is solid, ...

A. Overview of hippocampal dynamics during movie watching. FMRI data from the hippocampus were measured at the voxel level, and low-dimensional subspaces for two types of novelty and memorability were ...

Memory loss and "brain fog" may be long-term side effects of COVID-19, according to researchers. In a recent study published last week in the journal JAMA Network Open, Mt. Sinai Health System experts ...
