Activity in one brain structure can predict people's preferences

The study shows that even when people rate options similarly, they will choose the one that causes more activation in the caudate nucleus, a brain region involved in anticipating reward.

Gulf War veterans display abnormal brain response to specific chemicals

A new study by UT Southwestern Medical Center researchers is the first to pinpoint damage inside the brains of veterans suffering from Gulf War syndrome - a finding that links the illness to chemical exposures and may lead to diagnostic tests and treatments.
