Fifty-seven cases of unilateral cerebral lesions were examined to study the influence of cerebrum on eye movements. For eye movement examinations, spontaneous nystagmus, optokinetic nystagmus and eye tracking movements were observed and recorded by ENG. 1. Directional preponderance to the lesion side was seen. 1) In frontal and parietal lobe lesions, spontaneous nystagmus to the lesion side was mainly seen. 2) In frontal, parietal, occipital lobe lesions and in cases of cerebral hemorrhage, OKN to the lesion side was better provoked than OKN to the normal side. OKN to the lesion side was also impaired only in cases of the lesions including the parietal lobe. 3) In frontal, parietal lobe lesions and in cases of cerebral hemorrhage, there were more saccades to the lesion side in eye tracking movements. 4) Visual suppression was impaired in lesions of parietal lobe. 2. There was no dominant cerebral hemisphere in regard to eye movements.
