Brain Regions

Did you know that brain imaging studies have shown a correlation between larger brain regions and specific traits? Researchers at the University of Minnesota found that a part of the brain just above and behind the eyes, involved with considering rewards, was significantly larger in study subjects who exhibited a great deal of Extraversion. The study also correlated larger brain regions for a number of other traits: conscientiousness, which is associated with planning; neuroticism, a tendency to experience negative emotions that is associated with sensitivity to threat and punishment; and agreeableness, which relates to parts of the brain that allow us to understand each other's emotions, intentions, and mental states. Only openness/intellect didn't associate clearly with any of the predicted brain structures.
