Summary of Optic pathways and visual fields
Optic pathways begin in the retina and complete their course in the visual cortex of the central nervous system. Axons from the retinal ganglion cells form the optic nerves of cranial nerve II. After some fibers cross over at the optic chiasm, they continue as bilateral optic tracts to the lateral geniculate body of the thalamus. After ascending through the geniculocalcarine tract, axons from the lateral geniculate body synapse in the visual cortex on the banks of the calcarine fissure. It is in the cortex that visual processing and comprehension occurs.
