The basilar membrane runs down the middle of the cochlea and is displaced like a wave when the perilymph of the scala vestibuli is displaced by the stapes. This displacement helps to identify the profile of the sound impinging on the ear by acting like a series of band-pass filters.2 Sources - See all on Wikipedia
Basilar membrane - Wikipedia
When the vibration of the membrane rocks the triangular frames, the hairs on the cells are repeatedly displaced, and that produces streams of corresponding pulses in the nerve fibers, which are transmitted to the auditory pathway. [9] . See more
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 … See more
The basilar membrane is a pseudo-resonant structure that, like the strings on an instrument, varies in width and stiffness. But unlike … See more

Basilar Membrane - an overview | ScienceDirect Topics
Displacement of the basilar membrane clearly stimulates the hair cells of the organ of Corti, which act as transducers in converting mechanical displacement into changes in their membrane …
The Inner Ear - Neuroscience - NCBI Bookshelf
As a result of this structural arrangement, inward movement of the oval window displaces the fluid of the inner ear, which causes the round window to bulge out slightly and deforms the basilar …

Basilar membrane: Anatomy and function - Kenhub
Oct 30, 2023 · Sound waves of varying frequencies will displace different parts of the basilar membrane along its length in a gradient-like fashion. Closer to the base of the cochlea, the membrane is narrower and stiffer and so will be …

Perception Lecture Notes: Frequency Tuning and Pitch Perception
For sinusoidal (pure tone) sounds, each point on the basilar membrane oscillates up and down at the same frequency as the sound. What differs from point to point is the size of the oscillation. …
Basilar Membrane - an overview | ScienceDirect Topics
Although low-frequency sounds produce maximal displacement at the apex of the basilar membrane, they also produce displacement at the base due to the traveling wave’s …
Stiffness was measured over a 24-pm range of static displacements of the basilar membrane and is presented as stiffness versus static displacement.
Basilar Membrane - an overview | ScienceDirect Topics
Intensity discrimination depends on the length of the basilar membrane set in motion and the amplitude of the vibration. Displacement of a longer area of the membrane activates more …
Minimal basilar membrane motion in low-frequency …
Jul 12, 2016 · We show that low-frequency sound moves a small portion of the basilar membrane, and that the motion declines in an exponential manner across the basilar membrane. Hence, the response of the hearing organ to speech …
The Basilar Membrane and Fourier Analysis - Hanover College
The displacement of the basilar membrane in response to frequency is quite specific. Each location along the basilar membrane responds to a characteristic frequency. Any sound will …
Basilar membrane displacement related to endolymphatic sac …
The displacement of the basilar membrane in the apical and middle segments that may occur with endolymphatic hydrops, to the extent that it impinges on the interscalar septum, is related to a …
Basilar_Membrane - Simon Fraser University
Incoming vibrations set up a travelling wave along the membrane giving it a different maximum displacement for different frequencies as shown below. The bulging of the membrane creates …
Models for approximating basilar membrane displacement
Three analytical models are developed for estimating the displacement of the basilar membrane in the human ear when the sound pressure at the eardrum is known. Frequency-domain data, …
Basilar Membrane - an overview | ScienceDirect Topics
The amount of basilar membrane displacement is proportional to stimulus level, but for tones with frequencies near BF displacement, it is a nonlinear compressive function of sound level.
Place Code Theory - Hanover College
The base of the basilar membrane is tightly wound and thus more responsive to high frequencies, whereas the apex is loose and responsive to lower frequencies. Indeed, the displacement of …
