THE INTERICTAL electroencephalographic study of patients with psychomotor attacks led one of us (B. F.), with Gibbs and Gibbs, to admit in 1947* that this type of epileptic manifestations was accompanied by an anterior temporal epileptogenic focus, either unilateral or bilateral. This statement was confirmed by numerous subsequent investigations.
Nevertheless, more recent observations have led us to change our opinion and to admit the possibility of clinically primary automatisms (or psychomotor attacks) being likewise produced by discharges originating outside the temporal lobe, even when clinically they may not fall within the category of postictal automatisms.
In 1952 one of us (B. F.) with Schroeder and others7 showed that an epileptogenic discharge originating in silent areas of the frontal cortex might produce typical psychomotor attacks.
Further, in some cases studied the subcortical origin of the psychomotor attacks had been suspected. Peculiar features of the interictal EEG suggested the possibility that
