In turn, the bipolar cells (the 2° visual afferent) synapse with retinal ganglion cells and amacrine cells, which enhance contrast effects that support form vision and establish the basis for movement detection. ![]() Within the retina, the receptors synapse with bipolar and horizontal cells, which establish the basis for brightness and color contrasts. The previous chapter described how the light-sensitive receptors of the eye convert the image projected onto the retina into spatially distributed neural activity in the first neurons of the visual pathway (i.e., the photoreceptors). The visual system is unique as much of visual processing occurs outside the brain within the retina of the eye.
