Exploration of the meninges and brain in situ

Striate arteries, anterior commissure and optic nerve viewed from above and in front

More tissue has been cut away from the basal region of the left hemisphere. The anterior commissure (6) has been partly removed. The striate arteries and the recurrent branch of the anterior cerebral artery (17) are shown in their relation to the lentiform nucleus. The temporal pole has been removed from the middle cranial fossa.
