웹2015년 7월 31일 · We proposed a piezoelectric artificial basilar membrane (ABM) composed of a microelectromechanical system cantilever array. The ABM mimics the tonotopy of the cochlea: frequency selectivity and mechanoelectric transduction. The fabricated ABM exhibits a clear tonotopy in an audible frequency range (2.92–12.6 kHz). 웹2024년 3월 15일 · These results allow to study the mapping of the excitation frequency to its characteristic pattern along the basilar membrane, called tonotopy. Further, the spatial …
웹2024년 2월 24일 · The human cochlea transforms sound waves into electrical signals in the acoustic nerve fibers with high acuity. This transformation occurs via vibrating anisotropic … 웹2024년 2월 8일 · Relative to the other sensory systems, axon guidance in the auditory system is particularly poorly understood. Tonotopy—the organization of sound frequencies along an axis—is evident in the basilar membrane of the cochlea and all brainstem and central auditory centers (reviewed in Appler and Goodrich, 2011 ).
웹2016년 6월 8일 · A triboelectric-based artificial basilar membrane (TEABM) can mimic cochlear tonotopy by triboelectrification between Kapton film and aluminum foil. The two … 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 …

웹2024년 4월 3일 · Auditory pathway. The external ear/pinna funnels sound waves into a unidirectional wave, and is able to direct it into the auditory canal. This sound then reaches the tympanic membrane, and causes it to vibrate. The louder the sound the bigger the vibration, the lower pitch the sound the slower the vibration. integrationskurs a2웹2024년 9월 18일 · Frequency-to-place mapping, or tonotopy, is a fundamental organizing principle from the earliest stages of auditory processing in the cochlea to subcortical and cortical regions. Although cortical maps are referred to as tonotopic, previous studies employed sounds that covary in spectral content and higher-level perceptual features such … joe hice웹2012년 2월 13일 · Tonotopy of the bushcricket crista acustica in Mygalopsis marki was first mapped by Oldfield using intracellular recordings of the sensory neurons ... However, unlike the basilar membrane in mammals that is surrounded by fluid on both sides, the CA is loaded with fluid on top and air below (see Fig. S1). joe hickle city of wichita웹MEMS flexible artificial basilar membrane fabricated from piezoelectric aluminum nitride on an SU-8 substrate-Wide-range frequency selectivity in an ... Due to the tonotopy, specific locations of the BM are activated that depend on the frequency components of the incoming sound. As the BM joe hickey rock networks웹2024년 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.
