EVOKED-POTENTIALS OF THE LATERAL GENICULATE-BODY DURING SACCADIC SUPPRESSION OF VISION IN CATS

Evoked potentials of the lateral geniculate body were examined in cats during gaze holding and horizontal saccades elicited by a short flash against a homogeneous background. Statistical analysis showed that the positive component of evoked potentials recorded during gaze holding from the lateral geniculate body contralateral to the direction of the saccade did not differ from their positive component during: saccades, but that the differences between the corresponding negative components were significant (p<0.01). Under the same conditions, both the positive and negative components of evoked potentials from the lateral geniculate body ipsilateral to the saccade's direction were found to be significantly suppressed during saccades but not during gaze holding.
