Sagittal view of the basal ganglia and internal capsule. The corona radiata is a massive fan-shaped white matter sheet that is continuous ventrally with the internal capsule. Corticospinal, corticobulbar and corticopontine fibers are carried via the corona radiata and internal capsule to the brainstem and spinal cord.  The globus pallidus lies lateral to the internal capsule and is separated by the posterior limb of the internal capsule from the thalamus (not visible in this dissection).   The uncinate fasciculus lies ventral to the head of the caudate nucleus and interconnects the anteromedial region of the temporal lobe with the orbitofrontal cortices.  (Image courtesy of AL Rhoton, Jr.)
