The parvocellular neurons of the visual system receive their input from midget cells, a type of retinal ganglion cell, whose axons are excite the optic tract. These synapses occur in one of the four dorsal parvocellular layers of the lateral geniculate nucleus. The information from each eye is kept separate at this point, and continues to be segregated until processing in the visual cortex. The elect… WebIn general, midget cells have red–green opponency, parasol RGCs are achromatic, and bistratified ganglion cells connect with S-cone ON and L-M cone OFF pathways. …
