God a light /Rodontic comes in from ↓ Ins Off Bipolar (21) O s but Huns On Bipolar cell. retinal On opti neve bara s Almost all cones are centered in fovea (details), which is the center of the macula. • Ex. Helps us search for Waldo. o Phototransduction cascade: what happens when light hits rod/cone § Light hits rods (which causes rod turns off) à bipolar cell (turns on)à retinal ganglion cell (turns on) à optic nerve à BRAIN. § The phototransduction cascade is the process of rod turning from ON à OFF § 20
