Patients with the damage to the orbital region of the prefrontal cortex and monkeys with lesions in this area show impairment in emotional and motivational behavior. They also have difficulty in the extinction of learned behavior and in the reversal learning. This brain area is concerned with not only the value estimation of reward and aversive stimuli but also the expectation of these stimuli. The lateral prefrontal cortex plays an important role in the integration of emotion/motivation and cognition. The medial prefrontal cortex is concerned with action selection based on the previous reward history. The ventrolateral prefrontal cortex that comprises the anterior parts of the orbital and inferior medial prefrontal cortex plays an important role in emotion-based decision-making.
