WebThe classical receptive field of a ganglion cell is defined as the area of the retina where stimulation with a small spot of light produces a change in ganglion cell firing rate. Ganglion cells are classified into three basic types based on their responses to light stimuli presented in the centers of their receptive fields. In the visual system, receptive fields are volumes in visual space. They are smallest in the fovea where they can be a few minutes of arc like a dot on this page, to the whole page. For example, the receptive field of a single photoreceptor is a cone-shaped volume comprising all the visual directions in which light will alter the firing of that cell. Its apex is located in the center of the l…
