Norepinephrine released in the locus coeruleus during fear learning is accompanied by increased calcium and cAMP levels in nearby astrocytes.
The degree of neuronal synchrony between the anterior cingulate cortex and the hippocampus during recall is an indication of memory age (in mice).
Scientists have found evidence that hippocampal memories of experience are not stored in place cells.
In addition to encoding self location, brain cells in the rat hippocampus act like a GPS that encodes the location of other rats.
Scientists use optogenetics to discover a part of the brain necessary for retrieving memories of personal experiences.
