Mechanical properties of basilar membrane.

A fresh basilar membrane has different mechanical properties in the radial and in the longitudinal directions. When pressure with a needle is exerted on the basilar membrane, a narrow radially oriented strip is deflected. The form of the deflection can be deduced from the pathological consequences of the acoustic trauma as well. The observed anisotrophy is a property of the vital membrane and is disturbed by chemical and physical influences and is lost post mortem. The post-mortem changes can explain the results obtained by von Békésy which differ from ours. The physiological meaning of the mechanical properties of the basilar membrane is discussed here.

Cochlear micromechanics.

On the basis of functional morphology, biomechanical properties and topographic relations of the cells of the Corti organ, a physical model was designed for the study of mechanical action in the cochlear partition during sound stimulation. The topographic relations between the supporting and the sensory cells of the organ of Corti transform the basilar membrane deviation into a complex movement of the reticular lamina, which enhances the differences in the deviation of stereocilia of the inner and outer hair cells.
