This article reviews the literature on the modeling of auditory transducer dynamics. Theoretical descriptions and computational models of transducer dynamics are presented and discussed.
Since the introduction of the gating-spring model of hair cell mechanotransduction in 1983, theories of auditory transducer dynamics have been developed along with the accumulation of electrophysiological and mechanical data. Recent findings suggest that the auditory transduction apparatus might be very similar across vertebrates and invertebrates, and that auditory transducer dynamics can shape the performance of entire hearing organs.
The sense of hearing relies on a small number of transduction modules that convert minute mechanical stimuli into electrical signals. Models have been proposed that describe how this transduction works. These models may help to understand the biophysics of mechanoelectrical signal transduction, the contribution of transducer dynamics to auditory signal processing, and to link transducer function and genes.
本文回顾了有关听觉换能器动力学建模的文献。文中呈现并讨论了换能器动力学的理论描述和计算模型。
自1983年引入毛细胞机械转导的门控弹簧模型以来,随着电生理和力学数据的积累,听觉换能器动力学理论不断发展。最新研究结果表明,脊椎动物和无脊椎动物的听觉转导装置可能非常相似,并且听觉换能器动力学可以塑造整个听觉器官的性能。
听觉依赖于少数将微小机械刺激转化为电信号的转导模块。已经提出了描述这种转导如何工作的模型。这些模型可能有助于理解机电信号转导的生物物理学、换能器动力学对听觉信号处理的贡献,以及将换能器功能与基因联系起来。
