Adult neurogenesis, already appreciated for its role in learning and memory, also participates in mental health and possibly even attention, new research suggests.

Rats and equations help researchers develop a theory of how our brains keep track of when events took place.

Signals from the lateral entorhinal cortex help create “time cells” in the hippocampus, according to some researchers.

Cutting-edge microscopy is revealing how new neurons made in adult mice’s brains tap into existing neuronal connections.

Honeybees can remember reward-associated odors three days after a single learning experience.

Those who had developed PTSD appear to be less able to suppress unwanted memories—traumatic or not—suggesting a role for the general ability to control memory recall in the disorder.

Under constant darkness, Drosophila’s ability to form lasting memories is impaired.

Strategies to make lab animals forget, remember, or experience false recollections probe how memory works, and may inspire treatments for neurological diseases.

The animals develop a new memory that overrides the fearful one by inhibiting the cells that encode the original memory.
