The OFC, like the DLPFC, is involved in the cognitive processing of decision making; however, because of its close connection with the limbic system, it is particularly associated with our ability to make decisions based on emotional information. The OFC also plays a major role in forming social attachments and regulating emotions. This region can be thought of as a convergence zone for sensory and emotional information, effectively integrating external and internal worlds. Social information is processed and used to guide us in our perceptions and interactions, and the OFC plays an important role in the interpretation of these complex social interactions, including, for example, the ability to understand a joke. The OFC may help us predict the reactions of others and modulate our behaviour accordingly. When there is a dysfunction in the orbitofrontal cortex, the normal cortical–subcortical modulation is not optimal—as is likely the case in borderline personality disorder. As with other areas of the PFC, the OFC has hemispherical differences. The left OFC is associated with positive emotions, while the right OFC is associated with more negative emotions.
