Morphology of on-off direction-selective ganglion cells in the rabbit retina

Abstract

On-off direction-selective ganglion cells in rabbit retina have been stained by intracellular injection of horseradish peroxidase (HRP). The dendritic ramification is basically bistratified . Global asymmetries related to the preferred direction are not apparent, but the small diameter dendrites, spines, and complex branching pattern are consistent with models based on local, non-linear mechanisms for direction-selectivity.
