Seattle scientists have zeroed in on a part of the brain that seems to have an interesting job: motivating the brain’s owner to exercise. The findings could have implications for understanding depression.
The dorsal medial habenula is a little structure tucked inside the brain, above the brainstem. Psychiatrist Eric Turner of Seattle Children’s Research Institute knew it had something to do with regulating mood, but not a lot more.
“People asked me, 'Well, what does it do?' And I actually didn’t know. And when I looked it up I found that very little is known about this area of the brain,” he said.
