Document Summary

Ganglion cells: bipolar axons synapse with ganglion dendrites with amacrine cells what inhibit some messages. Visual acuity: ability to see fine detail is greatest when the visual image projects directly into fovea. Blind-spot: ganglion cells exit through the back of the eye near the fovea creates a blind spot (no photoreceptors) Rods and cones contain visual pigments, light hits them and two different chemicals are produced. Rods: produce pigments called rhodopsin (red, then turns to bleached) bleaching is very easy, stare into bright light, they when you look away everything is white and hard to see, happens because pigments have been bleached. Cones: pigments called chloroblabe (green), erythrolabe (red), cyanolabe (blue) shows that vision is made of three colours, responsive to different colours. Photopigments: rods and cones translate light waves into nerve impulses through actions of protein molecules. Absorption of light by molecules produce a chemical reaction that changes the rate of neurotransmitter release.
