Visual Pathway
The pathway:
Vision is generated by photoreceptors in the retina, a layer of cells at the back of the eye.
The information leaves the eye by way of the optic nerve, and
There is a partial crossing of axons at the optic chiasm.
After the chiasm, the axons are called the optic tract.
The optic tract wraps around the midbrain to get to the lateral geniculate nucleus (LGN), where all the axons must synapse.
The LGN axons fan out through the deep white matter of the brain as the optic radiations
Optic radiations will ultimately travel to primary visual cortex, at the back of the brain.
