He was also responsible for the numbering of the cranial nerves, still used to this day. He called his discovery the "circulus arteriosus cerebri". It is named after the English physician Thomas Willis (1621–1675), who first described the anatomy of his circle in 1664 in his book "Cerebri anatome: cui accessit nervorum descriptio et usus" (The Anatomy of the Brain and Nerves). See persistent carotid-vertebrobasilar anastomoses. When present, it is functionally a single artery that supplies the brainstem and cerebellum (often associated with aneurysms). It courses through the hypoglossal canal, parallel to the nerve, connecting the cervical ICA with the basilar artery.
