Color and intense light, found in fovea, less of them
Holds cones/ accute vision
Exit point of retina, optic nerve
Synapses with photoreceptors
Synapses with bipolar cells and then axons come together to form optic nerve
Parallel to back of retina, combine messages
From Photopigment to Ganglion Cells
Tiny molecules of R/Cs made of opsin/retinal. When light touches are bleached and turn from pink to yellow. This hyperpolarizes the cell causing it to stop releasing glutamate. This makes bipolar cells depolarize which releases neurotransmitter to depolarize ganglion cells. This excited ganglion cells sending action potentials down optic nerve.
Dorsal Lateral Geniculate Nucleus
Input from retina to thalamus to visual cortex.
In geniculate nucleus; form, movement, depth, and small light differences.
In geniculate nucleus; color, fine details
Sublayer, blue wavelength transmission
