Hippocampal neurons that store abstract memories of prior experiences activate when new, but similar events take place.
Stimulating the posterior cingulate cortex increased hippocampal gamma-band power and strengthened the connections between the two brain regions. Using deep brain stimulation could help to treat memory disorders and cognitive impairment.
Researchers investigate why two people who experience the same event often have different memories of what occurred.
IDIBELL researchers have discovered a mechanism that allows us to segment experiences into memory units. Rapidly reactivating memories can lead to long term memory consolidation, they note.
