Rod input to amacrine cells in dace retina.

Intracellular recordings in dace retina demonstrate a type of amacrine cell whose responses to flashes of light were characteristically a transient depolarization at the onset of light, followed by a slow decay toward the dark level, similar to rod-dominated, AII amacrine cells described in cat retina. Electron microscopy of HRP-filled dace AII-like amacrine cells suggested that they receive significant rod inputs through rod-dominated bipolar cells.
