WebThe bipolar cells are of two kinds—“on” and “off”—responding to either an increase or a decrease in local light intensity. The roles of the amacrine cells are less clear, but they contribute to the organization of the … WebThe now active bipolar cells in turn stimulate the ganglion cells, which send action potentials along their axons (which leave the eye as the optic nerve). Thus, the visual system relies on change in retinal activity, rather than the absence or presence of activity, to encode visual signals for the brain. immigration non profit nyc
