Herophilus, Erasistratus, Aretaeus, and Galen: ancient roots of the Bell–Magendie Law

Abstract: ✓Since the early 19th century, significant controversy has persisted over the competing claims of two men, Charles Bell and François Magendie, to a pivotal discovery: that the dorsal spinal roots subserve sensation, whereas the ventral spinal roots subserve motion. However, the foundations of neuroanatomy on which Bell and Magendie built their research was formed two millennia in advance. Exploration of the work of four ancient scholars—Herophilus, Erasistratus, Aretaeus, and Galen–reveals a remarkable… Show more

“…However, according to Galen’s writings (centuries earlier), 10 Herophilus and Erasistratus had already noted the separate neural pathways for motor and sensory functions. 24,25 ○ He recognized and differentiated the spinal and cranial nerves, and he demonstrated that the nerves of the spinal cord were directly attached to the brain. He described at least seven pairs of cranial nerves and designated six of them as follows: optic, oculomotor, trigeminal, facial, auditory and hypoglossal.…”

“…Herophilus proceeded also in detailed dissection and description of the cranial and spinal nerves, distinguishing them and their roots into sensory and motor ones. 17 Herophilus by his meticulous neuroanatomical observations concluded that the brain was definitely the dominant organ in Man (the hegemonicon, the governing principle of the body), which motivates and controls all bodily actions and activities. 18 Erasistratus of Chios or Ceos (304-250 BC) was recognized as one of the most famous neurologists in the Hellenistic period.…”

“…Although Charles Bell and François Magendie, have both claimed the honor of discovering that dorsal spinal roots mediate sensation and ventral spinal roots carry motor fibres, it is believed that ancient anatomists such as Herophilus and Erasistratus had already appreciated the separate neural pathways during their time (Tomey et al, 2007). It is suggested by Rufus in De anatomia partium hominis that both of them knew of the existence of "two kinds of nerves," that could either induce "voluntary motion" or are "capable of sensation" (Rocca 2003).…”
