Researchers used neuroimaging technology to show the creation and elimination of synapses between neurons in the brains of living mice. The findings provide insight into what happens when memories are created and forgotten. The research could pave the way for new treatments for PTSD.
A shared set of brain regions play a vital role in the retrieval of weak memories.
Hippocampal neurons that store abstract memories of prior experiences activate when new, but similar events take place.
Stable memories are encoded by teams of neurons firing in synchrony, providing redundancy that enables the memory to persist over time.
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.
Researchers have identified a network of cells in the entorhinal cortex that appear to play a key role into putting experience into a temporal context.
A new study reveals how neurogranin and FMRP help encode memories of new places.
Researchers report resting for 10 minutes after learning a new piece of information helps us to create and retain more detailed memories.
Manageable levels of anxiety can help people to better recall details of events, researchers report.
MIT researchers have identified a brain network that allows the brain to record memories of new places.
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.
