Overview of Cerebral Function
Limbic lobe
The limbic lobe (limbic system) includes structures that receive inputs from diverse areas of the brain and that participate in complicated, interrelated behaviors (eg, memory, learning, emotion). Lesions that affect the limbic system usually result in a variety of deficits. Patients with epileptogenic foci in the medial limbic-emotional parts of the temporal lobe commonly have complex partial seizures, characterized by uncontrollable feelings and autonomic, cognitive, or emotional dysfunction. Occasionally, such patients have personality changes, characterized by humorlessness, philosophic religiosity, and obsessiveness. Patients may have olfactory hallucinations and hypergraphia (an overwhelming urge to write).
