A problem which has followed Homo sapiens throughout history is that of the composition and localization of the mind, including the question of its very existence. Presently, the relevance and intensity of this discussion is greater than ever--models have been developed as a result of recent insights into the various aspects of biology, as they relate to both the natural and human sciences. In the second part of this book we will return to this enormously dynamic field--not "beyond reductionism" ( Koestler), but between an essentially reductionistic way of treating certain problems and the simultaneous (and not contradictory) recognition of holistic and synergic views and values. Here we shall concentrate on a condensed picture of major trends in current brain research concerning the localization of perceptual, cognitive, and emotive functions in the two halves of the brain.
Before proceeding, an examination of historical data will prove useful. For further study I recommend the accounts given by two neurophysiologists that, although of different generations, are
