Sicherer Flug mit Zoom-Effekt

Studie untersucht, wie sich Fledermäuse räumlich orientieren

(PresseBox) (München, )
Fliegen ohne zu sehen: Fledermäuse orientieren sich mithilfe von Schallwellen und der vielfältigen Echos, die ihre Umgebung zurückwirft. Ihr inneres Navigationssystem erweist sich dabei als ausgesprochen flexibel, wie eine Studie in Nature Communications zeigt: Je näher Fledermäuse an einem Objekt vorbeifliegen, umso mehr Neuronen sind in dem Gehirnareal aktiv, das die akustischen Signale räumlich verarbeitet. Diese Informationen helfen den Flugkünstlern, blitzschnell zu reagieren und Hindernissen auszuweichen.

Nachtaktive Fledermäuse haben sich perfekt auf ein Leben ohne Licht eingestellt. Sie senden Ortungslaute aus, um aus dem zeitverzögerten Echo die Entfernung zu einem Hindernis oder Beutetier zu berechnen. In ihrem Gehirn existiert eine uwwqgzok fsjbnsuqgs Njtfs cik dxfoyaogaftnirjk Lspnrqtrhfcrqt.
