which artery supplies the medial surface of the cortex including the hypothalamus
Thalamus The thalamus derives its blood supply from a number of arteries: the polar artery (posterior communicating artery), paramedian thalamic-subthalamic arteries, inferolateral (thalamogeniculate) arteries, and posterior (medial and lateral) choroidal arteries.[9] These are all branches of the posterior cerebral artery.[10]
