[4] Dissections of human cadavers were banned in most places at the time, except for Alexandria. %PDF-1.6 % Revern, R. (2015). This led him to further dissect the eye, and in so doing to discover the cornea, the retina, the iris, and the chorioid coat. 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. Veins were believed to be filled with blood and a mixture of air and water. Herophilus' fame made the school a success. In his account of the heart and its function, he distinguished between pulmonary and systemic circulation; he appears to have been very close to discovering the circulation of the blood, a feat eventually achieved by English physician William Harvey in 1628.

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 .
