Zusammenfassung
Unser Innenohr umfasst dezidierte vestibuläre und auditorsiche Sinnesorgane für die Messung von Gravitation, Dreh-Beschleunigung, und Schall [24], [13]. Im Herzen dieser Organe sitzen spezialisierte mechanosensorische Zellen, die so genannten Haarzellen, welche durch Gravitation, Dreh-Beschleunigung bzw. Schall ausgelöste Auslenkungen ihrer sensorischen Haarbündel in elektrische Antworten wandeln [26]. Der genetische Modellorganismus Drosophila melanogaster, die Frucht- oder Taufiege, besitzt weder Haarzellen noch ein Innenohr im engeren Sinne, ist aber wie wir in der Lage, Schall und Gravitation zu messen [31]. Neuere Untersuchungen haben verblüffende funktionale und genetische Parallelen zwischen Hör- und Gravitationssinn bei Mensch und Fliege aufgedeckt, die Letztere für die Analyse grundlegender Mechanismen des Hörens und Gravitationssinns prädestinieren [14].
