Exploration of the brain from its basal aspect

Relations of tip of inferior horn of lateral ventricle

The medial portion of the right temporal lobe, including the uncus and part of the hippocampal structures, has been cut away. The inferior horn of the lateral ventricle is thus opened and the choroid plexus exposed. The arachnoid membrane is intact in several areas.

1 .	Lateral cerebral fissure (Sylvian)
2 .	Middle cerebral artery
3 .	Internal carotid artery (cut across)
4 .	Anterior perforated substance
5 .	Choroidal artery (anterior)
6 .	Amygdaloid nucleus (partially removed)
7 .	Cerebral peduncle
8 .	Inferior horn of lateral ventricle
9 .	Hippocampus (cut across)
10 .	Posterior cerebral artery
11 .	Hippocampal gyrus
12 .	Collateral fissure
13 .	Internal auditory artery
14 .	Facial nerve (VII) and vestibulocochlear (VIII)
15 .	Glossopharyngeal (IX) and vagus (X) nerves
16 .	Accessory nerve (XI)
17 .	Olfactory tract
18 .	Straight gyrus
19 .	Optic nerve (II)
20 .	Anterior cerebral artery
21 .	Infundibulum
22 .	Pituitary
23 .	Uncus (hippocampal gyrus)
24 .	Oculomotor nerve (III)
25 .	Basilar artery
26 .	Pons
27 .	Trigeminal nerve (V)
28 .	Abducens nerve (VI)
29 .	Medulla oblongata (pyramid)
