Retinal ganglion cell

A retinal output neuron conveying information through action potentials. Its responses reflect inputs transformed by retinal circuitry rather than a direct copy of one cone voltage.

A retinal ganglion-cell type with dendrites in two strata, identified with an S-ON opponent pathway in Primates. Anatomy and physiology together establish a distinct route for S-cone signals; the traditional blue-on label does not equate its discharge with unique blue experience.

A retinal ganglion-cell type whose central retinal circuitry can support fine spatial sampling and cone-opponent responses. Functional spatial and chromatic roles need not correspond to entirely separate anatomical channels.
