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. 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 ...

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 ...

In the brains of adult mice, communication through astrocyte networks controls the formation of spatial memories and plasticity in the hippocampus, a new study led by scientists at the Institute of ...

Dynamic mechanisms of engram maturation. During the allocation, engram allocation is primarily governed by enhancements in intrinsic neuronal excitability, driven primarily by increased ...

Innovative brain-wide mapping study shows that 'engrams,' the ensemble of neurons encoding a memory, is widely distributed including among regions not previously recognized. A new study by scientists ...

When a new memory forms the brain undergoes physical and functional changes known collectively as a “memory trace.” This memory trace represents the specific patterns of neuronal activity and ...

Memory is a continually unfolding process. Initial details of an experience take shape in memory; the brain’s representation of that information then changes over time. With subsequent reactivations, ...
