Inferior View of the Optic Radiations

Surgical Correlation

Tags

Inferior view of the optic radiations. The temporal horn of the lateral ventricle has been opened to reveal the optic radiations within the temporal lobe. The optic nerve is visible on the inferior surface of the frontal lobe. The optic tracts arise from the optic chiasm and proceed posterolaterally to synapse in the lateral geniculate body of the thalamus. The optic radiations arise from the lateral geniculate body and course anteriorly into the temporal lobe, then posteriorly just superior to the temporal horn of the lateral ventricle toward the occipital lobe. Also visible on the inferior aspect of the frontal lobe is the olfactory tract, which divides posteriorly into the medial and lateral olfactory striae just anterior to the anterior perforated substance. (Image courtesy of AL Rhoton, Jr.)
