UNSOLVED PROBLEMS SUGGESTED BY CEREBELLAR CONNECTIONS AND CEREBELLAR HISTOLOGY

Abstract

The neurologic sciences probably have never experienced the dissociation between the anatomic and physiologic points of view that is so bitterly complained of elsewhere in the present dynamic welter. Consequently, probably everyone who has been occupied with neuroanatomic problems has always sought to interpret his observations more or less in terms of function as well. The purpose of this paper is to voice the obstacles of such functional interpretation which are due to lacunae in the knowledge of neuro-anatomy and of which nearly every one working in this line is aware; hence, the banal character of these few reflections—at least to neuro-anatomists. It may be that before this paper is published, some of the questions raised will have received their answers. Broadly speaking, when one deals with the central nervous system as a whole or with any portion of its gray matter or even with any individual neuron, three questions
