The effect of vitamin A, thiamine and ascorbic acid on the optic nerve action potential was measured with the oscillograms, typical patterns of which had been obtained givining electrical slimulation to the optic nerve extripated from mice and guinea pigs. Thiamine deficient rats showed a maked decrease in the susceptibility of the optic nerve, which however could be effectively restored following thiamine injection. Thiamine combined with prehormone, activated the function of the normal optic nerve. Vitamin A deficiency also resulted in almost the same disfunction of the optic nerve, against which vitamin A injection was fairly effective. The effect of vitamin A on the function of the optic nerve, however, was much less than that of thiamine. No significant disfunction of the optic nerve was observed in ascorbic acid deficient guinea pigs.
