Abstract

Most investigators place reflective beads on the basilar membrane to measure its vibration with optical methods. It is therefore important to find out if the beads faithfully follow the motion of the structures on which they are placed. Vibration of the beads on the basilar membrane and basilar membrane adjacent to the beads are measured in the third turn of the guinea pig cochlea in a temporal bone preparation. It is shown that the beads do not follow the motion of the organ. The mechanism by which this departure may occur is investigated by modeling the motion of the beads on the Claudius' cells.

摘要

大多数研究人员会在基底膜上放置反光珠，以便用光学方法测量其振动。因此，弄清楚这些珠子是否能如实跟随它们所放置结构的运动就很重要。在颞骨标本中，在豚鼠耳蜗的第三圈测量基底膜上珠子的振动以及与珠子相邻的基底膜的振动。结果表明，珠子并不跟随器官的运动。通过对克劳迪乌斯细胞上珠子的运动进行建模，研究了这种偏差可能发生的机制。
