The physiology of the nervous system and the functional differentiation of its component parts has been but recently investigated, and is now in many particulars so well established that it seems proper before entering the domain of neurologic pathology to briefly recapitulate, not only that which has been scientifically proven, but the many speculations of eminent investigators that are as yet mere hypotheses. Without going into a detailed history of the evolution of cerebral physiology, I will refer to the great advance made by the anatomists of the seventeenth century. Before that time anatomy and physiology were necessarily theoretical, for as a basis they rested on speculation and tradition, not on the dissection of the human body.
