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 ...

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 ...

With its ageing population, the prevalence of dementia in Hong Kong is expected to increase. Healthcare researchers from The Hong Kong Polytechnic University (PolyU) have developed an innovative ...

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 ...

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 ...

Fear memory encoding, the process responsible for persistent reactions to trauma-associated cues, is influenced by a sparse but potent population of inhibitory cells called parvalbumin-interneurons ...

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 ...

Our new study shows why time feels like it speeds up with age. The good news: Older adults cherish and recall their ...

While stress can have both positive and negative effects on memory, chronic or prolonged stress is more likely to impair ...
