The basilar membrane is a pseudo-resonant structure that, like the strings on an instrument, varies in width and stiffness. But unlike the parallel strings of a guitar, the basilar membrane is not a discrete set of resonant structures, but a single structure with varying width, stiffness, mass, damping, and duct dimensions along its length. The motion of the basilar membrane is generally described as a traveling wave. The properties of the membrane at a given point along its length … WebApr 11, 2024 · The cochlear nuclei, located in the dorsal brainstem, receive incoming auditory stimuli via the spiral ganglion neurons (SGNs) and are the first site of auditory processing. ...
