WebbThus far you have heard about four kinds of processing of the visual input that occur within the retina: 1) The convergence of cones and rods on retinal ganglion cells. 2) The splitting of the photoreceptor output into separate ON and OFF channels. WebbThe three major groups of so-called feature detectors in visual cortex include simple cells, complex cells, and hypercomplex cells. Simple cells are the most specific, responding to lines of particular width, orientation, angle, and position within visual field.
