ELECTROPHYSIOLOGICAL STUDIES ON HALLUCINATION

Abstract

EEG findings in schizophrenia have been discussed by a number of workers. Various types of abnormalities have been described, including major paroxysmal discharges in a small proportion of cases. The authors have investigated the significance of photic activation procedure, the correlation between EEG and psychopharmacological treatment and the longitudinal study of each case in schizophrenic patients. From these studies, attention was focused on the correlation between photically activated theta waves and hallucination. Then we are interested in the correlation between activated theta waves and the existence, frequency, intensity (or content) of hallucination and patient's attitude to it. For this purpose, a number of patients with hallucination are needed as the subjects. This paper attempts to provide some data on these problems obtained in schizophrenic patients with hallucination.
