Abstract
A cochlear postmortem preparation has been developed which allows for hydromechanical studies of the transilluminated organ of Corti. It was found that cochlear hair cells act as optical waveguides. This property of hair cells is important for optical cochlear investigations. It may be used in the study of the motion of single hair cells. Es wurde eine Methode zur Herstellung von schwingungsfähigen Oberflächenpräparaten des postmortalen Cortischen Organs entwickelt. Während des Schwingvorganges kann das Cortische Organ mit Licht durchstrahlt werden. Es wurde gefunden, daß cochleare Haarzellen als optische Wellenleiter wirken und in dieser Eigenschaft optischen Glasfasern sehr ähnlich sind. Die Lichtleitereigenschaft der Haarzellen kann in optischen Untersuchungen der Funktionsweise des Innenohrs ausgenutzt werden. So kann sie benutzt werden zur Untersuchung des Schwingverhaltens einzelner Haarzellen.Keywords
