>Our primary finding is that when compared to Caucasians, an African-American cohort exhibited smaller cerebral volumes but larger absolute left OFC volumes. Additionally, the OFC and amygdala appear to occupy a significantly greater proportion of the total cerebral volume in the African-American cohort.
The orbitofrontal cortex has been found to represent not only the reward value and expected reward value of foods and other reinforcers, but also their subjective pleasantness.
