Method |
"The object of the work to be described is a quantitative analysis of the mechanical properties of the hair bundles. The approach has been to measure the bending of a single bundle in the turtle cochlea by attaching it to a flexible glass fibre, and monitoring the fibre's motion through its shadowing of a light beam falling on a photodiode array." |
Comments |
"Under conditions where the fibre adhered strongly to a bundle, it was possible to compare stiffness values for motion towards and away from the kinocilium [="a special type of cilium on the apex of hair cells located in the sensory epithelium of the vertebrate inner ear.", wiki]. This comparison was performed in three cells, and did not reveal any major asymmetry in the steady-state stiffness, an observation which differs from that of Strelioff & Flock (1984). In the three experiments, the mean ratio of stiffnesses for motion towards and away from the kinocilium was 0.91." |
