Recent advances in recording technique have reawakened interest in the interrelationship of electroencephalographically detectable cerebral activity and both normal and abnormal behavior. Much of this attention has centered about dysfunction of the temporal lobe and its subcortical connections in regard to disordered behavior. In particular, Heath and associates13 have reported a specific electrophysiologic abnormality in these brain areas in schizophrenia. An interest in temporal lobe disorders has also been fostered by the study of psychical seizures, which have long been of clinical importance because of their similarity to psychotic states. Gibbs7 and Hill8 have emphasized the incidence of personality disorders in temporal lobe dysfunction, and Hill has called attention to the presence, in such patients, of "episodic behavior" other than epilepsy, i. e., acute catatonic states and impulsive emotionality.
The aim of our study has been to investigate the behavior of a group of patients with known
