Exploration of the brain from the medial aspect

Retrolenticular and sublenticular parts of internal capsule; striate arteries

The remainder of the lentiform nucleus has been taken out and the optic tract removed. The retrolenticular (12) and sublenticular (15) parts of the internal capsule are visible. The anterior perforated substance is cut away to reveal the course of the lateral striate arteries from the middle cerebral artery through the area of the lentiform nucleus. The medial inferior region of the frontal lobe is cut away.
