Introduction

Abstract

Human beings consider themselves as “individuals”. However, they relate their individuality not so much to their physical uniqueness as to the unique character of the thoughts and accumulated experiences in their heads. They proudly defend the inaccessibility of these, and derive from them the freedom of thought. On the other hand, they are intrigued by the functioning of the material substrate of their individuality. This question provides the major source of motivation for investigations of the nervous system. Thus it is not surprising that many more scientists are attracted by research into the brain and its functioning, than by studies of any other organ of the body. Man wants to inquire into his nature.
