had correctly identified the cause of scabies as a parasite. Lancisi however felt scabies was of humoral origin. Because of Lancisi’s powerful position and, because previous scientists like Galileo Galilei had fallen into disgrace, Bonomo was silenced and his discovery was forgotten until the modern era. Studies on the brain and the soul Lancisi described the corpus callosum as the "seat of the soul, which imagines, deliberates and judges." His Dissertatio Physiognomica provided the supporting argument in 1713. He opposed alternative locations of the soul as hypothesized by others, such as the centrum ovale, by Andreas Vesalius, and the pineal gland, by René Descartes. He hypothesized that the longitudinal striae (later named in his honor as the "striae lancisi" or "nerves of Lancisi") were the conduit between the anterior location of the soul, and the posterior location of sensory organ functions, both within the corpus callosum.
