[Interhemispheric interrelationships in oligophrenic patients].

The author registered evoked electrical activity from the right and left occipatal area in oligophrenic patients to letters and nonverba stimula presented unilateraly to different halves of the field of vision. For control purposes a group of normals was studied according to the same method. A hemispheric asymmetry seen in the group of normals was not detected in oligophrenic patients. It is assumed that this is one of the nervous mechanisms of declined intellectual activity.
