Introduction The orbitofrontal cortex has been found to be associated with the processing of cognitive information related to decision making. That is, responding to the reward or punishment outcomes experienced by an individual after making a decision and responding to the expectation of facing that outcome later. This region of the brain is involved in regulating emotions during decision making, thus causing an individual to engage in certain social behaviors. This essay will briefly discuss the associations between social behavior decision making and its relationship to emotion, empathy, and inhibition. Orbitofrontal cortex and its location The image above (The orbitofrontal cortex, 2014) shows the location of the orbitofrontal cortex a. medially and b. ventrally. The medial dorsal nucleus of the thalamus is located in areas 4 and 6, i.e. in the anterior part of the motor and premotor cortices of the frontal lobe. The medial part of this nucleus (magnocellular part) projects to the ventral medial orbital portion of the prefrontal lobe (Kringelbach, 2005). This particular portion of the prefrontal cortex is called the orbitofrontal cortex of the brain and is made up of Brodmann areas 10, 11, and 47. It receives input from the ventral visual stream and input from taste, somatosensory, and olfactory receptors (Kringelbach, 2005). The orbitofrontal cortex is associated with the limbic system, including the amydala, and the dorsolateral prefrontal cortex. The association with the limbic system includes connection to the insular cortex, parahippocampal regions, and the hippocampus (Cavada et al., 2000). The limbic system influences the control of behavior and emotions in an individual...... middle of paper...... & Mishkin, 1970; Roberts & Wallis, 2000; Rolls, 2000). Therefore, it can be concluded that lesion in this area of the brain could result in uninhibited behavior that influences social behavior. Conclusion There is evidence that the orbitofrontal cortex is associated with emotions and decision making, and injury to this area can cause severe impairments in the process of using emotions to make decisions before performing certain tasks. Therefore, patients with orbitofrontal damage may suffer from an inability to make appropriate choices by acting impulsively. Furthermore, they may ignore the consequences of their behaviors since they will not be able to understand the thoughts and emotions experienced by other people. Finally, they may engage in uninhibited social behaviors such as obsessive gambling, hypersexuality, drug and alcohol abuse, and excessive use of swear words..
