Abstract

Kein anderes Organ ist so komplex wie das Gehirn: Über 100 Milliarden Nervenzellen und über 100 Billionen Synapsen sorgen für die Steuerung unseres Körpers. Hirnforschung versucht die Geheimnisse dieses Superorgans zu ergründen. Dabei will sie nicht nur die Funktionsweise des Organs verstehen, sondern auch die Verknüpfung der Hirntätigkeit mit unserer Wahrnehmung, unseren Gefühlen und Denkprozessen. Der Hirnforschung geht es um die Erklärung des unerklärten Universums in mir selbst , sagt Wolf Singer, Direktor am Max-Planck-Institut für Hirnforschung in Frankfurt am Main. Matthias Eckoldt versammelt in diesem Buch Gespräche mit führenden deutschen Hirnforschern, die auf der gesamten Breite des Wissenschaftsfeldes arbeiten. Dabei zeigt sich der Philosoph und Wissenschaftsjournalist am aktuellen Stand der Neurowissenschaft ebenso interessiert wie an deren Grenzen. Die Gespräche drehen sich um Neuroprothetik, die Wirkweise von Psychopharmaka, Ton- und Sprachverarbeitung im Gehirn, um Strategien und Strukturen des Gedächtnisses, um besondere Eigenschaften neuronaler Netze, konkurrierende Paradigmen und um die Wahrheitsproblematik. Ein philosophisches Lesevergnügen und eine exklusive Einführung in die Hirnforschung aus erster Hand. Gespräche mit: Gerald Hüther, Wolf Singer, Gerhard Roth, Hans J. Markowitsch, Angela D. Friederici, Christoph von der Malsburg, Frank Rösler, Henning Scheich, Randolf Menzel.

Abstract

What is consciousness? How do physical processes in the brain give rise to the self-aware mind and to feelings as profoundly varied as love or hate, aesthetic pleasure or spiritual yearning? These questions today are among the most hotly debated issues among scientists and philosophers, and we have seen in recent years superb volumes by such eminent figures as Francis Crick, Daniel C. Dennett, Gerald Edelman, and Roger Penrose, all firing volleys in what has come to be called the consciousness wars. Now, in The Conscious Mind, philosopher David J. Chalmers offers a cogent analysis of this heated debate as he unveils a major new theory of consciousness, one that rejects the prevailing reductionist trend of science, while offering provocative insights into the relationship between mind and brain. Writing in a rigorous, thought-provoking style, the author takes us on a far-reaching tour through the philosophical ramifications of consciousness. Chalmers convincingly reveals how contemporary cognitive science and neurobiology have failed to explain how and why mental events emerge from physiological occurrences in the brain. He proposes instead that conscious experience must be understood in an entirely new light--as an irreducible entity (similar to such physical properties as time, mass, and space) that exists at a fundamental level and cannot be understood as the sum of its parts. And after suggesting some intriguing possibilities about the structure and laws of conscious experience, he details how his unique reinterpretation of the mind could be the focus of a new science. Throughout the book, Chalmers provides fascinating thought experiments that trenchantly illustrate his ideas. For example, in exploring the notion that consciousness could be experienced by machines as well as humans, Chalmers asks us to imagine a thinking brain in which neurons are slowly replaced by silicon chips that precisely duplicate their functions--as the neurons are replaced, will consciousness gradually fade away? The book also features thoughtful discussions of how the author's theories might be practically applied to subjects as diverse as artificial intelligence and the interpretation of quantum mechanics.
