Exercise improves memory, boosts blood flow to brain

Scientists have collected plenty of evidence linking exercise to brain health, with some research suggesting fitness may even improve memory. But what happens during exercise to trigger these benefits?

Observing the freely behaving brain in action

Scientists working at Caesar have developed a small head-mounted microscope that allows access to the inner workings of the brain. The new system enables measurement of activity from neuronal populations located in the deep cortical layer with single-c…

Found: Brain structure that controls our behavior

Solving problems, planning one’s own actions, controlling emotions — these executive functions are fundamental processes for controlling our behavior. Despite numerous indications, there has not yet been any clear evidence to support which brain areas…

Not all multiple sclerosis-like diseases are alike

Scientists say some myelin-damaging disorders have a distinctive pathology that groups them into a unique disease entity.

Brain-to-gut connections traced

Using rabies virus injected into the stomach of rats, researchers trace the nerves back to the brain and find distinct ‘fight or flight’ and ‘rest and digest’ circuits. These results explain how mental states can affect the gut, and present new ways to…

How experiencing traumatic stress leads to aggression

Traumatic stress can cause aggression by strengthening two brain pathways involved in emotion, according to new research. Targeting those pathways via deep brain stimulation may stymie aggression associated with post-traumatic stress disorder.

The brain’s facial recognition area doesn’t differentiate outgroup members

A quirk in how the brain processes faces makes it harder to tell members of a racial outgroup apart, according to new research.

Scientists find brain center that ‘profoundly’ shuts down pain

A research team has found a small area of the brain in mice that can profoundly control the animals’ sense of pain. Somewhat unexpectedly, this brain center turns pain off, not on. It’s located in an area where few people would have thought to look for…

Maintaining heart health may protect against cognitive decline

People with a higher risk of developing cardiovascular disease have increased cognitive decline, including an increase in typical markers of Alzheimer’s disease, suggesting that monitoring and controlling for heart disease may be key to maintaining and…

Personal accounts of childhood maltreatment matter more for mental health than records

Personal accounts of childhood maltreatment show a stronger association with psychiatric problems compared to legal proof that maltreatment occurred, according to a new study.
