Thalamus and internal capsule
Webthe caudate nucleus and the thalamus are medial to the internal capsule; the putamen and globus pallidus are lateral to the internal capsule. These relations reflect the course of the outgrowing axons that formed the internal capsule in fetal development as they navigated through the anlage of deep gray matter in the embryonic brain. WebThe anterior limb of the internal capsule conveys the bulk of the prefrontal and anterior cingulate interaction with thalamus (mostly the medial dorsal and the anterior thalamic nuclei), and focal lesions of the anterior limb, or genu, of the capsule essentially disconnect these nuclei from their cortical targets, producing a complex behavioral syndrome. 77–79 …
