Lateral View of the Globus Pallidus and Optic Radiations

Surgical Correlation


Lateral view of the globus pallidus and optic radiations.  The inferior limiting sulcus of the insula separates the insula from the superior temporal gyrus of the temporal lobe. The anterior commissure has been transected as it courses laterally, immediately ventral to the globus pallidus, towards the temporal cortices.  The fan-shaped optic radiations originate from the lateral geniculate nucleus of the thalamus (located further medially and not visible in this dissection) and course posteriorly through the parietal and temporal lobes to the primary visual cortex.  (Image courtesy of AL Rhoton, Jr.)
