ABSTRACT
We describe some component processes that contribute to emotional reactions and suggest heir localization in brain and some ways in which they interact. We then review findings relating emotional processing to the integrity of particular cerebral areas in the light of this model. The model invokes anterior-posterior and lateral specialization of cerebrum. The posterior sector provides data necessary to maintain homeostasis. The anterior sector exerts control to stabilize as needed. The left sided data-control facility deals with external change and ongoing action; the right sided data-control facility deals with internal change interrupting action, and control of emotional arousal. We attempt to show that this model is consistent with the specialization of brain areas for emotional processing as inferred from findings on focally brain damaged, psychopathological and normal populations.
