The Circle of Willis is located at the base of the brain. The term refers to a junction between the arteries that supply blood to the brain. It is formed at the end of the right and left internal carotid arteries. Leaving the circle are the blood vessels of the brain itself - the "cerebral arteries". Great answer, it is the mass of arteries that circle around each other in the junction for the brain, I didn't realize they were at the base of the brain. I thought they were more towards the front and middle, kind of, behind the eyes, (sorry for the big technical terms). But I haven't heard it described better.
