Change in the reflex organization of the visual receptor in response to thermal cutaneous stimulation

Summary It was shown by perimetry that when the skin is heated or cooled the setting of the human visual system under constant conditions of dark adaptation changes in such a way that the reciprocal relationship between the rod and cone system is retained. Heating the skin caused the rod field to be reduced, but the cone field was increased. Cooling caused the reverse change, i.e., the rod field increased and the cone field was reduced. These functional changes in the visual system induced by cutaneous thermal stimulation are evidently brought about reflexly.(Presented by Active Member SSSR V. V.
