, and ends in the internal cerebral vein (vein of Galen
); it receives tributaries from the interpeduncular fossa
, the inferior horn of the lateral ventricle, the hippocampal gyrus, and the mid-brain.
Anterior perforated substance
The anterior perforated substance is an irregularly quadrilateral area in front of the optic tract and behind the olfactory trigone, from which it is separated by the fissure prima; medially and in front, it is continuous with the subcallosal gyrus; it is bounded laterally by the lateral stria of...

- (a) a small anterior cerebral vein which accompanies the anterior cerebral artery and supplies the medial surface of the frontal lobe by the fronto-basal vein.
- (b) the deep middle cerebral vein (deep Sylvian vein), which receives tributaries from the insulaInsular cortexIn each hemisphere of the mammalian brain the insular cortex is a portion of the cerebral cortex folded deep within the lateral sulcus between the temporal lobe and the frontal lobe. The cortical area overlying it towards the lateral surface of the brain is the operculum...
and neighboring gyri, and runs in the lower part of the lateral cerebral fissure, and - (c) the inferior striate veins, which leave the corpus striatum through the anterior perforated substance.
The basal vein passes backward around the cerebral peduncle
Cerebral peduncle
Mainly, the three common areas that give rise to the cerebral peduncles are the cortex, the spinal cord and the cerebellum. The cerebral peduncle, by most classifications, is everything in the mesencephalon except the tectum. The region includes the midbrain tegmentum, crus cerebri and pretectum...

Vein of Galen
The great cerebral vein is one of the large blood vessels in the skull draining the cerebrum . It is also known as the "vein of Galen" , named for its discoverer, the Greek physician Galen. However, it is not the only vein with this eponym....
); it receives tributaries from the interpeduncular fossa
Interpeduncular fossa
The Interpeduncular fossa is a somewhat lozenge-shaped area of the base of the brain, limited in front by the optic chiasma, behind by the antero-superior surface of the pons, antero-laterally by the converging optic tracts, and postero-laterally by the diverging cerebral peduncles.The structures...
