Abstract

Lateral gaze aversions which follow reflective or thought provoking questions are called conjugated lateral eye movements (CLEMs). This response was studied in 20 schizophrenic patients, 20 depressive patients and 20 healthy controls. Frontal and parietal EEG measures were recorded simultaneously with the question/answer task. There were no differences in CLEMs among the 3 groups. Schizophrenic and depressive patients demonstrated a significantly reduced EEG-power on the left and an increased power on the right in comparison with healthy controls. This may point to a functional interhemispheric 'disconnection' in patients. Comparative correlations revealed EEG-power increase during the occurrence of contralateral CLEMs in the whole 10 min task.
