Abstract

Neuronen sind die Grundbausteine des Gehirns. Ein Neuron ist eine einzelne Zelle, welche darauf spezialisiert ist, schnelle Spannungsänderungen sowohl an seiner eigenen Membran, als auch in benachbarten Neuronen zu ermöglichen. Ein Gehirn ist eine Ansammlung einer Vielzahl solcher Zellen. Diese Vielzahl von Neuronen ist im Gegensatz zu einem einzelnen Neuron zu so erstaunlichen Dingen wie "Sehen", "logisch Denken" oder "Erinnern" fähig. Es erscheint auch sehr wahrscheinlich, dass psychologische Prozesse physischer Natur sind, welche sich im Gehirn abspielen
