[Neurophysiological study of short-latency potentials in central structures of visual system and their relations to additional oscillations in retina].
In chronic experiments on alert rabbits, the formation of short-latency positive and negative potentials preceding initial responses, in wide range of light intensities in visual structures, were revealed. The observed potentials were registered in retina under light intensity of 100-120 J. In corpus geniculatum laterale, colliculus superior and visual cortex, they were initiated under 30 J, 15-50 J and 50 J, respectively. The relations of these potentials to light stimulus intensities were studied.
