The Answer is The answer should include the following information: When researchers gave participants a questionnaire assessing the Big Five personality traits and then scanned the participants' brains, they found a number of correlations between personality and brain structure. First, extraversion was associated with larger brain tissue volume in the medial orbitofrontal cortex, a brain area that is associated with sensitivity to rewarding stimuli. Agreeableness was associated with increased volume in the posterior cingulate cortex (a brain region associated with understanding the beliefs of others) and the fusiform gyrus, an area of the cortex associated with face perception. Conscientiousness was associated with the middle frontal gyrus, which is involved with planning, working memory, and self-regulation. Neuroticism was associated with a mixed pattern of structural differences. Higher levels of neuroticism were associated with a pattern that researchers interpreted as systems related to threat and punishment-reduced volume in one area of the hippocampus and increased volume in the mid-cingulate cortex, an area associated with pain sensitivity. There were no significant patterns associated with openness to experience.
