Nervenzellen in den Augen von Fliegen und Wirbeltieren spalten optische Informationen ähnlich auf

(PresseBox) (München, )
Das Auge ist nicht nur eine Linse, die Bilder aufnimmt und in elektrische Signale umwandelt. Wie bei allen Wirbeltieren trennen auch im menschlichen Auge Nervenzellen das Gesehene bereits in der Netzhaut in verschiedene Bildkanäle. Diese vorsortierten Informationen werden dann als parallele Bildsequenzen an das Gehirn weitergeleitet. Dass Fruchtfliegen optische Informationen ganz ähnlich verarbeiten, fanden jetzt Wissenschaftler des Max-Planck-Instituts für Neurobiologie in Martinsried heraus. Vermutlich ist diese Art der Verschaltung besonders energiesparend und wird daher über die verschiedensten Tierarten hinweg beibehalten. (Nature, 11. November 2010)
