Dopamine ‘gas pedal’ and serotonin ‘brake’ team up to accelerate learning
Mice learn fastest and most reliably when they experience an increase in dopamine paired with an inhibition of serotonin in their nucleus accumbens, a new study shows, helping to resolve long-standing questions about the neuromodulators’ relationship.

Putting a bright idea to the test
A surprising wave of findings in mice suggests that light and sound flickering at 40 hertz clears the brain of Alzheimer’s-disease-linked plaques. Several companies are hoping to prove it works in people.

Learning or performance? Why the distinction matters for memory science
New methods make it possible to probe the neural substrates of memory with unprecedented precision. Making the most of them demands careful experimental design.

Newly found hypothalamus circuits shape bullying behaviors in mice
Activity in the tiny brain region helps submissive rodents learn to avoid aggressors, and aggressive mice to curb their attacks, according to two recent studies.

Immune-activation model mice escape infantile amnesia, retain early memories
Male pups born to mothers treated with immune-stimulating molecules show autism-like behaviors and, unlike wildtype animals, do not lose memories formed during early life.
