Sagittal View of the Basal Ganglia and Cerebral White Matter Tracts

Sagittal view of the basal ganglia and cerebral white matter tracts. The corona radiata is a massive, vertically-oriented, fan-shaped collection of white matter tracts.  It contains a mixture of ascending sensory fibers (mainly thalamocortical fibers) and descending motor fibers (e.g., corticopontine, corticobulbar, and corticospinal tracts).   The corona radiata is continuous ventrally with the internal capsule and dorsally with the centrum semiovale.  The globus pallidus and putamen collectively make up the lenticular (or lentiform) nucleus of the basal ganglia.  The globus pallidus lies medial to the putamen and lateral to the internal capsule.  The rostral and inferior portion of the putamen fuses with the anteroinferior head of the caudate nucleus (not visible in this dissection) to form the nucleus accumbens, or ventral striatum.  The uncinate fasciculus is an associational fiber bundle that connects the ventral frontal lobe with the anteromedial temporal lobe. The inferior longitudinal fasciculus carries cortico-cortical association fibers between the anterior temporal lobe and occipital lobe. (Image courtesy of AL Rhoton, Jr.)
