Inferior view of the visual pathways of the brain. Afferent visual information is transmitted from the optic nerves to the optic tracts through the optic chiasm. Fibers containing information from the inferior retinal quadrants emanate from the lateral geniculate body as “Meyer’s loop” by looping anteriorly, then posteriorly, around the temporal horn of the lateral ventricle to terminate in the lingual gyrus. Also visible from this view is the anterior perforated substance, just anterior to the optic tracts. (Image courtesy of AL Rhoton, Jr.)
