"There is wide variability in ganglion cell types across species. In primates, including humans, there are generally three classes of RGCs: • W-ganglion: small, 40% of total, broad fields in retina, excitation from rods. Detection of direction movement anywhere in the field. • X-ganglion: medium diameter, 55% of total, small field, color vision. Sustained response. " - Ganglion receptive fields are
