Inferior view of the optic tract and radiations. The temporal horn of the lateral ventricle has been removed to reveal structures at the axial level superior to the temporal horn. The amygdala is cross-sectioned, as is the head of the caudate. Optic tracts containing information from one hemifield proceeds posterolaterally just medial to the amygdala, synapsing in the lateral geniculate nucleus of the inferior thalamus. Optic radiations course anterolaterally, then posteriorly just superior to the temporal horn of the lateral ventricle. (Image courtesy of AL Rhoton, Jr.)
