      Nineteen temporal lobectomy patients with epilepsy were evaluated (11 right and 8 left) with a brief questionnaire that addressed: (1) General Happiness; (2) Depression; (3) Anxiety; (4) Impulse Control; and (5) Socialization. The patients with left temporal lobectomy reported increases in depression and decreases in socialization compared with the right temporal lobectomy patients after surgery. Furthermore although the right temporal lobectomy patients reported increases in general happiness, no changes in general happiness were reported by the left temporal lobectomy patients. The present study supported the idea that an increased negative affect is associated with left rather than right temporal lobectomy. This is consistent with a model of negative emotional valence when the right hemisphere dominates awareness.
