FUNCTION OF MAMMALIAN RETINA DURING X-IRRADIATION.
Abstract
The electrical potentials elicited by light and low-dose X- irradiation were measured within the vitreous body of the eyes of rabbits. Nerve block agents and pharmacological degeneration of the visual receptors support the conclusion that although the eye is excited by X-rays the excitation does not occur at the site(s) responsible for light reception. The results are consistant with neural interaction effects, specifically, interactions with the lateral inhibitory system which encodes retinal information and increases the sharpness of figure-ground relationships. These findings are inconsistant with photopigment bleaching by X-rays which has been suggested as the basis for visual excitation by ionizing rays of all energies. (Author)
