People who show low social engagement over long periods of time often show reductions in cognitive function. Studies of the brain may provide clues about this correlation.

The activation of young brain cells in adult mice is necessary not just for forming memories, but consolidating them during rapid eye movement sleep, a study shows.

A new study in mice does not find evidence supporting two popular ideas for the mechanism for bridging the temporal time gap between two paired stimuli.

A fluorescent image of murine hippocampal cells is the winning microscopy image from more than 400 submissions from 65 countries for Olympus’s 2019 Image of the Year Award.

Memory formation in mice involves coordinated activity at the cellular level that likely leads to new circuits in the brain.

By trimming synapses in the adult mouse hippocampus, microglia help facilitate forgetting.

The silicon chips receive and send electrical signals, recreating activity from neurons in the rat brain that play a role in breathing and thinking.

New, unpublished results show some of the cells produce new neurons for up to 90 days, much longer than a previously identified set of neural stem cells that only generate neurons for a month or two.

Conflicting results on the existence of new neurons in adults have researchers designing new ways to identify and count neuronal progenitors—and finally get to the bottom of neurogenesis.
