Einem deutsch-spanischen Forscherteam ist es erstmals gelungen, in einem Säugetiergehirn nicht nur die Anzahl der Nervenzellen zu erhöhen, sondern einen sehr gering ausgeprägten falten- und furchenlosen Cortex (Großhirnrinde) zur Ausprägung von Falten zu bringen. Die Wissenschaftler um Dr. Federico Calegari vom DFG-Forschungszentrum für Regenerative Therapien Dresden - Exzellenzcluster der TU Dresden (CRTD) und Dr. Víctor Borrell vom Instituto de Neurociencias de Alicante und der Universidad Miguel Hernández haben einen Mechanismus entdeckt, der den Prozess der Faltung in Gang setzt und auch wieder stoppt. Die Falten und Furchen vergrößern die Gehirnoberfläche, damit automatisch die Anzahl der dort sitzenden Nervenzellen. Die Ergebnisse jpyp dkoqg tr Upmcnjzngke "Omw EHXM Zulevjn" ipbpfqwhpevxaf fdvmrj (NRB: 33.5804/ekwzu.5577.94).
