A new study suggests that stress-reduction treatment for adolescents who've been through war can change their biology for the better.

The Boston researcher who examined the brain of former football star Aaron Hernandez says it showed the most damage her team had seen in an athlete so young.

Hernandez, whose on-field performance for the New England Patriots earned him a $40 million contract in 2012, hanged himself in a prison cell earlier this year while serving a life sentence for murder. He was 27 years old.

When people don't get enough sleep, certain brain cells literally slow down.

A study that recorded directly from neurons in the brains of 12 people found that sleep deprivation causes the bursts of electrical activity that brain cells use to communicate to become slower and weaker, a team reports online Monday in Nature Medicine.

People who are thinking about killing themselves appear to have distinctive brain activity that can now be measured by a computer.

In these people, words like "death" and "trouble" produce a distinctive "neural signature" not found in others, scientists report in the journal Nature Human Behaviour. More than 44,000 people commit suicide in the U.S. each year.

Scientists in Seattle have created three-dimensional computer reconstructions of living human brain cells by studying tissue that is usually discarded during surgery.

Fresh evidence that the body's immune system interacts directly with the brain could lead to a new understanding of diseases from multiple sclerosis to Alzheimer's.

A study of human and monkey brains found lymphatic vessels — a key part of the body's immune system — in a membrane that surrounds the brain and nervous system, a team reported Tuesday in the online journal eLife.

The family of Aaron Hernandez has filed suit against the NFL after it was revealed by an autopsy that the former Patriots player had advanced degenerative brain disease when he died. 

The brain of former New England Patriots star Aaron Hernandez showed severe signs of the degenerative brain disease chronic traumatic encephalopathy, referred to as CTE, according to doctors who conducted tests after he committed suicide in April while imprisoned for murder.

Why We All Scream When We Get Ice Cream Brain Freeze

Jul 31, 2017

Ah, the brain freeze — the signature pain of summer experienced by anyone who has eaten an ice cream cone with too much enthusiasm or slurped down a slushie a little too quickly.

But have you ever stopped mid-freeze to think about why our bodies react like this?

Well, researchers who study pain have, and some, like Dr. Kris Rau of the University of Louisville in Kentucky, say it's a good way to understand the basics of how we process damaging stimuli.

But first, a lesson in terminology.
