Not illustrated. 1901 edition. Excerpt: ... of the higher sensory nerves." "In addition to its great simplicity this definition has still another advantage, namely, that it is satisfied by a single experiment; because of the two elements of which the definition is made up, one element is always given anatomically. This is the higher sensory nerve, whose presence also vouches for its function. The one experiment that it is necessary to make has to prove that in addition to the sensory apparatus the general centre of movement also exists. The proof is then complete if the one-sided removal of the central nervous part so changes the direction of the movements of the animals that a circus-motion, which is generally known by the name forced movement, takes the place of a forward movement" (Steiner). This idea is likewise erroneous and easily leads to absurdity. Onesided destruction of the cerebral hemispheres in man produces no forced movements. Thus, according to Steiner, the cerebral hemispheres should not belong to the brain. Second, according to Steiner, the ear must be a brain. One-sided lesion of the ear is sure to produce forced movements in a series of animals, and, moreover, the auditory nerve is a higher sensory nerve. I have mentioned this subject at this place because it is a typical illustration of what plays on words in physiology lead to. It is not our task to find a definition for the word brain, but to gain an insight into the functions of the central nervous system. It is of minor importance what name we give to the different parts of the central nervous system. In connection with this chapter we wish to call attention to the more recent experiments of Sherring-ton and H. E. Hering, from which it seems to follow that with the innervation of a muscle the relaxation of...

DOWNLOAD EBOOK →Excerpt from Comparative Physiology of the Brain and Comparative Psychology: An One-Act Comedy in Verse It is the purpose of this book to serve as a short introduction to the comparative physiology of the brain and of the central nervous system. Physiology has thus far been essentially the physiology of Vertebrates. I am convinced, however, that for the establishment of the laws of life-phenomena a broader basis is necessary. Such a basis can be furnished only by a comparative physiology which includes all classes of the animal kingdom. My experience in the course on comparative physiology at Wood's Holl seems to indicate that the transition from the old to the comparative physiology can be most readily accomplished through the physiology of the central nervous system. The physiology of the brain has been rendered unnecessarily difficult through the fact that meta-physicians have at all times concerned themselves with the interpretation of brain functions and have introduced such metaphysical conceptions as soul, consciousness, will, etc. One part of the work of the physiologist must consist in the substitution of real physiological processes for these inadequate conceptions.
