Exploration of the meninges and brain in situ
Optic nerve, optic chiasm, optic tract and lateral geniculate body viewed from above and in front
The thalamus (2, 4) and internal capsule (20) have been cut away so that the optic tract (21) can be followed posteriorly from the optic chiasm to its termination at the lateral geniculate body (17). The left internal carotid artery (25) is visible within the chiasmatic subarachnoid cistern. A short distance above its point of emergence from beneath the anterior clinoid process the carotid bifurcates (22, lower pointer) into the anterior and middle cerebral arteries.
