. Anatomical, phylogenetical and clinical studies on the central nervous system. Nervous system. THE SIGNIFICANCE OF PHYLOGENETIC STUDIES FOR THE NEUROLOGIST For nine years I had the privilege of studying pathological anatomy of the nervous system at the Central Institute for Brainresearch, Amsterdam, conducted by Dr. C. U. Ariens Kappers. The phylogenetic development of the nervous system, studied there, deeply impressed me. As chnician and pathologist I worked out some subjects in this hne of science. In my opinion an exact knowledge of the relations in lower animals is valuable for the morphology, physiology and pathology of the human nervous system. Ontogenetic studies are of course no less important, but our knowledge in this line is far from complete. To give you an impression of the significance of the phylogenetic Hne of thought I desire to tell you something about my research work in this matter. Yesterday, in treating the pathology of sensibility, I gave some examples relating to physiological anatomy. Today I shall discuss morphology, pathological anatomy and clinical neurology. I begin with the cerebellum. In the older literature the human cerebellum was divided into a middle part, called the vermis with the flocculus and two lateral parts known as the hemispheres. EUiot Smith, Bradley and particularly Bolk divided the cerebellum differently. In studying several classes of mamimals they preferred a transverse division, while the former was sagittal. The figure 9 shows the scheme of the cerebellum after Bolk. There is an anterior part, called the lobus anterior and a posterior part, called the lobus posterior. These are sepa- rated from one another by a deep fissure, the sulcus pri- marius. In the lobus anterior no division can be made into middle and lateral parts. The lobus posterior is sub- 45.
