Exploration of the brain from its superior aspect
Systems of fibers related to head of caudate nucleus and putamen
The lentiform nucleus has been scraped away anteriorly and various bands of fibers which pass beneath it and the head of the caudate nucleus displayed. The temporal lobe has been cut back extensively.
1 . Fibers passing into head of caudate nucleus from internal capsule
2 . Longitudinal band of fibers beneath lentiform nucleus
3 . External capsule
4 . Middle cerebral artery
5 . Lateral striate artery
6 . Interior commissure
7 . Optic tract (cut across)
8 . Cerebral peduncle
9 . Hippocampus (cut across)
10 . Medullary substance of inferior temporal gyrus
11 . Cingulum (cut across)
12 . Genu corpus callosum
13 . Line along which ependymal lining of ventricle is reflected onto head of caudate nucleus
14 . Radiating fibers from rostral lamina corpus callosum
15 . Septum pellucidum
16 . Frontal part internal capsule
17 . Right column fornix (cut across)
18 . Left column fornix (cut across)
19 . Mamillothalamic tract (cut across)
20 . Fasciculus retroflexus
21 . Medial geniculate body
