Abstract
The amacrine cells in the salamander retina were identified by intracellular recording of photoresponses and staining with Procion yellow or Lucifer yellow. The characteristic amacrine cell response consists of a transient depolarization at both the onset and offset of illumination. Three morphological types of amacrine cell were recognized and correlated to different photoresponses. The small-field stratified amacrine cells respond to light stimulation with prolonged depolarizing waves. The multistratified amacrine cells exhibit sharp “on-off” depolarizing responses followed by shallow hyperpolarization. The large-field monostratified amacrine cell responses to small spots are transient depolarizations followed by slow hyperpolarizations while their responses to diffuse and peripheral illumination are transient depolarizations.

Dye-coupling, readily observed because of the low molecular weight and the intense fluorescence of the new dye, may serve as a general method of tracing certain functional connections by morphological means, and of studying the transfer of small molecules between cells.

The results suggest that the rapid transient on‐off activity in ganglion cells is mediated by opposing sawtooth shaped synaptic currents with different latencies, and it is inferred that each of these antagonistic imputs is generated by a regenerative depolarization in amacrine cells which then form synaptic inputs to the ganglions.

The results of this study provide insight into the retinal connections which underlie ganglion cell receptive field organization and raise the possibility that transmembrane movements of chloride ions are critical for the light responsiveness of horizontal and depolarizing bipolar cell activity.

Amacrine cell responses and their accompanying membrane resistance changes were studied in the carp retina and were found to be consistent with the assumption that bipolar cells liberate, when depolarized, a transmitter which is excitatory to the amacrine cells.

It follows then that only ganglion cell photoresponses originating from amacrines' input would be depressed by the nerve stimulation, which thus becomes a reliable test to discriminate whether ganglions originate fromAmacrine or bipolar inputs.
