title: Tetrodotoxin does not block the axonal transmission of S-potentials in goldfish retina.
abstract: Light-evoked responses (S-potentials) have been recorded from the somata and the axon terminals of horizontal cells of goldfish retinas. Data obtained in the controlled states of retinas and following tetrodotoxin (TTX) application show that TTX does not affect the quantitative relationships of the two sets of response potential. It is concluded that TTX does not influence the axonal transmission of S-potentials.
