thin brain

A study indicates that people who have a high family risk of developing depression had less brain matter on the right side of their brains:
[Dr. Bradley Peterson of Columbia University Medical Center and the New York State Psychiatric Institute] said having a thinner right cortex may increase the risk of depression by disrupting a person's ability to decode and remember social and emotional cues from other people.

They did memory and attention tests on the study subjects and found the less brain material a person had in the right cortex, the worse they performed on attention and memory tests.

"Our findings suggest rather strongly that if you have thinning in the right hemisphere of the brain, you may be predisposed to depression and may also have some cognitive and inattention issues," he said.
