Web7. A ganglion cell is a type of neuron in the retina of the eye that receives input from bipolar cells and processes visual information. A red ON center and green OFF surround ganglion cell is a type of color-opponent cell that responds to red light in the center of its receptive field and green light in the surrounding region. WebGanglion cells constitute the output pathway of the retina, transmitting highly processed and integrated signals to the visual processing areas in the brain. Up to 18 types of RGCs have …
