| Abstract: | During binocular stimulation of different sectors of the retina the amplitude of the two first postsynaptic components of the evoked potential in the superior colliculus to the second stimulus varies with the time delay between the testing and conditioning stimuli. Correlation is shown between the form of the evoked potential arising in response to the conditioning stimulus and the character of convergence of visual impluses in the superior colliculus. Qualitative differences are found in binocular interaction between sensory impulses depending on the way in which the conditioning impulses reach the region of the superior colliculus tested. An attempt is made to assess interaction between sensory volleys in the superior colliculus quantitatively.Institute of the Brain, Academy of Medical Sciences of the USSR, Moscow.
