Der Innere Kompass: Ein Richtungssinn im Gehirn

Tübinger Neurowissenschaftler weisen nach, dass "Kopfrichtungszellen" im Nagetiergehirn mit anderen Hirnstrukturen verbunden sind, die der Navigation dienen

(PresseBox) (Tübingen, )
Ein Neurowissenschaftler-Team unter Leitung von Dr. Andrea Burgalossi vom Werner Reichardt Centrum für Integrative Neurowissenschaften (CIN) der Universität Tübingen hat einen wichtigen Schritt hin zum Verständnis unseres “Inneren Kompasses” getan. Bei der Erforschung sogenannter Kopfrichtungszellen (Head Direction Cells bzw. HD-Zellen) in Nagetiergehirnen konnten sie die Existenz von Netzwerken nachweisen, die seit über einem Jahrzehnt lediglich theoretisch angenommen wurden: HD-Zellen sind direkt mit anderen Hirnstrukturen verbunden, die unsere Wegfindung im Raum ermöglichen. Besonders interessant ist der Befund, dass HD-Zellen Hirnareale ansteuern, in denen es viele Gitterzellen gibt. Von diesem Zelltypus wird vermutet, dass er bei der Navigation wie eine Art GPS uh Wtqehc xvrkl.
