Abstract

Mit 30 Watt erzeugt es Welten, von denen die schnellsten Computer nur träumen können. Das Gehirn besteht aus einfachen Elementen und produziert daraus Myriaden von Verknüpfungen. Dieses Wunderwerk der Selbstregulation ist bis heute nicht abschließend entschlüsselt. Wolf Singer, Neurophysiologe am Max-Planck-Institut für Hirnforschung in Frankfurt am Main, hat sein Leben der Erforschung dieses einzigartigen Organs gewidmet. Gemeinsam mit dem Denker Alexander Kluge kommt er ins Philosophieren.

"Da gibt's im Gehirn nicht eine Trennung zwischen Rechenwerk und Programmspeicher und Datenspeicher oder so was, sondern es gibt nur Neurone und deren Verschaltung. Und die Art und Weise, wie die verschaltet sind, nennen wir funktionelle Architektur, und da liegen die ganzen Geheimnisse, denn die Freiheitsgrade sind überschaubar, es kann nur variiert werden, wer mit wem kommuniziert, wie stark oder schwach die Kopplungen sind und ob sie hemmend oder erregend sind, wobei die allermeisten erregend sind. Und mit diesem Lego-Baukasten hat die Evolution die Großhirnrinde zusammengebastelt."
