웹2024년 4월 11일 · An necessary mechanism of tonotopy is the pliability of the stiffest part of the cochlear duct, the basilar membrane. Recall that the basilar membrane forms the border between the cochlear duct and the scala tympani. Note that the scale of the bony cochlea and those of the cochlear duct are inversely arranged: ... 웹The cochlea is a coiled, fluid-filled tube that is split into three chambers by two membranes, Reissner’s membrane and the basilar membrane (Fig. 53-4).

웹For biomimetic artificial basilar membrane (ABM), the frequency classification of basilar membranes depends on the principle of tonotopy [10–12]. Thus, the ABM covers all ranges of audible frequencies and induces local resonance in specific frequencies, at the same time. 웹Robert J. Zatorre, in Encyclopedia of the Human Brain, 2002 II.A Tonotopy. Tonotopic organization refers to the systematic topographical arrangement of neurons as a function of …

The basilar membrane is a stiff structural element within the cochlea of the inner ear which separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani. The basilar membrane moves up and down in response to incoming sound waves, which are converted to traveling waves on the basilar membrane. 웹(6 points) Place code: tonotopy on the basilar membrane ; Both. Temporal code [or timing code]: phase-locking of hair cell membrane potential (and spiral ganglion cell spikes) to match the frequency of sound ; Low frequencies only. 7. This image shows a hair cell with patch clamp electrode attached (bottom right).

웹2003년 1월 1일 · The basilar membrane, a flexible structure like a very long drumhead, separates scala tympani from scala media. The oval window connects to the scala vestibuli, so that the compression phase of each cycle increases pressure in the scala vestibuli and scala tympani, pushing down on the basilar membrane. The rarefaction phase pulls back up. 웹The manner in which the basilar membrane vibrates in response to sound is the key to understanding cochlear function. Measurements of the vibration of different parts of the basilar membrane, as well as the discharge rates of individual auditory nerve fibers, show that both these features are highly tuned; that is, they respond most intensely to a sound of a specific …
