WebWhat are the bipolar cells and ganglion cells? What makes up the optic nerve? Bipolar cells process and report light stimulation from rods and cones to ganglion cells. Ganglion cells produce action potentials that travel along their axons (the optic nerve) to the brain. What is the optic chiasm, and what happens there? WebThe changes induced in the rods and cones by light are transmitted to (3) a layer of neurons (nerve cells) called the bipolar cells. These bipolar cells connect with (4) the innermost layer of neurons, the ganglion cells; and …
WebThe primary pathway involves synapses from rods to ON-type rod bipolar cells with OFF signals reaching retinal ganglion cells (RGCs) via sign-inverting. IntroductionLight responses of rod photoreceptor cells traverse the retina through three pathways. The primary pathway involves synapses from rods to ON-type rod bipolar cells with OFF … WebP ganglion cells constituteabout 70% of the ganglion cells in the human retina. • Diffuse bipolar cells project to ganglion cells that are known as M ganglioncells (Figure 2.1 9) because they feed the magnocellular (“large cell”) layer of the LGN.
