Abstract

Information processing in the vertebrate retina occurs in two separate channels known as ON and OFF channels. When intracellular electrophysiological recordings were obtained from the perfused retina-eyecup preparation of the mud-puppy (Necturus maculosus), the addition of 2-amino-4-phosphonobutyric acid to the bathing medium blocked all responses in the ON channel but left intact the OFF responses including OFF ganglion cell discharge. 2-Amino-4- phosphonobutyric acid blocks the light response of the ON bipolar cell by mimicking the endogenous photoreceptor transmitter.
