Document Summary
Optic nerves carry output from sensory receptors through the optic chasm to cns. Carries neural impulses from retina to visual cortex. Leaves out the back of the retina. Hole in the retina where optic nerve forms. Small object that falls on blind spot is invisible. About half of visual information crosses over to the other side. Right side of visual field goes to right side of the brain. Left side of visual field goes to left side of the brain. Brain receives info from half of our right and left eye. Images stays together, information on the temporal side goes straight back. Neural energy travels to the lgn of the thalamus: primary processing occurs. Visual information gets relayed to the visual cortex (occipital lobe) : perception occurs.
