Two pairs of arteries supply blood to the brain: the vertebral arteries and the carotid arteries. The vertebral arteries converge near the base of the pons to form the unpaired basilar artery. The vertebral and basal arteries supply blood to the brain stem and cerebellum. At the level of the midbrain, the basilar artery splits into left and right superior cerebellar arteries and the posterior cerebral arteries. The posterior cerebral arteries send branches, called posterior communicating arteries, that connect them to the internal carotids. The internal carotids branch to form the middle cerebral arteries and the anterior cerebral arteries. The anterior cerebral arteries of each side are connected by the anterior communicating artery. Thus, the posterior cerebral and communicating arteries, the carotids, and the anterior cerebral and communicating arteries form a ring of connected arteries at the brain's base. This ring is called the 'circle of Willis'.

A personal request from Barry Thain, Clinical Hypnotist
This is the brochure site for my hypnotherapy practice. I put these pages here because I think hypnosis is all in the brain and, indeed, most of my work involves intervening in the supply of corticotropin releasing hormone from the bed nucleus of the stria terminalis.
Despite being a hypnotherapy site, these neuro-graphics pages get thousands of visits every month. (I've discovered they are used in Wikipedia so that explains a lot of it.) I hope this page has been useful to you, because it isn't of any use to me; unless ...
I have a hypnosis mp3 site. You would do me a great favour if you visited the site briefly because Google would notice and my site would become easier to find for those who want to download therapy. There's no trap, and you don't have to buy anything. There is a free (and popular, and effective) therapy called Appreciate Yourself that you are welcome to grab if you want to, but really I'd just appreciate the visit.
I'm afraid you'll find this request on all these pages, but you don't have to follow the link every time you see it. Once will be great!
Thanks in advance.
Barry
