Low-amplitude early negative potential preceding the positive component of primary responses to light was observed in the optic tract, superior colliculus, lateral geniculate body and visual cortex in chronic experiments with special recording schedule in rabbits. The early negative potential proved to be genetically connected with the "a"-wave of the electroretinogram. During the suppression of all but the "a"-wave ERG components with glycine, the early negative potential alone is preserved in the central structures of the visual system.
