    THE FUNCTIONS OF THE CEREBELLUM FIRST PART EXPOSITION OF FACTS CHAPTER I ANATOMY OF THE CEREBELLUM I. The Architecture of the Cerebellum The cerebellum is an unpaired median symmetrical organ, situated, in man, below the cerebral hemispheres which cover it entirely, behind the corpora quadrigemini, and above the pons Varolii and the medulla oblongata in which it makes a deep groove or concavity and which it overlaps largely on the sides. With its furrowed and lamellated appearance it is related to all the other parts of the central nervous system in which, by volume, it occupies the second place; it is but a misnomer to call it the little brain or Kleinhirn as do the Germans as this name is neither justified by morphology, histology nor physiology. The cortex of the cerebellum or the cerebellar mantle, which is demonstrated by a simple macroscopic examination, constitutes but one portion of the organ; a series of longitudinal or sagittal sections gives immediately an important idea of its architecture. From the surface towards the interior one can distinguish: (i) the cerebellar cortex; (2) a thick layer of white matter; (3) collections of gray matter or central gray nuclei. In man there are four of these nuclei for each half of the organ, the corpus rhomboideiim or cerebellar olive also called the corpus dentatum, the nucleus fastigii, the nucleus globulosus and the nucleus em-
