But he also took great pride in his century's extensive anatomical studies that had identified the optic, auditory, and olfactory nerves. And despite Descartes' insistence on the hollow nerve, the Scottish medical student John Moir record in his 1620 lecture notes: "nerves have no perceptible cavity internally, as the veins and arteries have."
