The purpose of this paper is to present some clinical data which suggests a relationship between abnormal electrical discharges in the depth structures of the temporal lobe and hallucinations. The information has been derived from a series of patients referred to the UCLA Neuropsychiatric Institute who suffered from temporal lobe epilepsy intractable to intensive pharmacologic regimes. The patients were studied with electrodes placed bilaterally in the depth structures of the temporal lobe as well as over the calvarium to monitor the electrical activity of the brain during the ictal and inter-ictal stages. If a unilateral focus for their seizures could be found, it was surgically excised in a second procedure aimed at alleviating their convulsive disorder. One of the patients studied presented initially with a complex hallucination as part of her seizure. In reviewing our series of patients it was of interest to note that hallucinations were produced by electrical stimulation of the depth structures of the temporal lobe in certain patients. The electrical stimulations were carried out in an attempt to induce seizure activity.
