For Herophilus, the ventricles were the seat of both soul and mental functions whereas Galen [27] later favoured the brain substance itself [27].Since the brain was the centre of the nervous system, there must be a passage from it, via the ventricles, into the cerebellum, for the spiritus animalis.Herophilus stressed the importance of the fourth . also the anatomy of the eye and medical terminology such as (in Latin translation "net like" becomes retiform/retina. It was Herophilus, then, who transferred to the nerves the function which Praxagoras had assigned to the arteries.

He was the first scientist to systematically perform scientific dissections of human cadavers. He discovered and named the torcular herophili, which he found by investigating the brain's cavities and following the sinuses of the dura mater (the tough, stringy membranes covering the brain and the spinal cord that lines the inner surface of the skull) to their meeting point at the sinuses. Gone were the days of Herophilus' dissection shows, but his scientific method and his learning have survived. To describe this final part of the artery he used the term meaning, presumably, that it resembled the sinews. ; IV.36, 12, Heiberg, ed.). ."
