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 ...

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 ...

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 ...

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

A new study in mice suggests that the brain creates multiple copies of memories, which enables it to regulate how they change over time. When you purchase through links on our site, we may earn an ...

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, ...

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 ...

In an important study for understanding how memories are made, cientists show that the flexibility of chromatin -- packaged DNA inside the cell -- plays a crucial role in 'deciding' which neurons are ...
