听觉和前庭系统的耦合毛细胞执行将声波和地面振动的能量转化为离子电流的关键任务。我们机械耦合组的生活，活跃的毛细胞与人工膜，从而模仿在体外的耦合动力系统。我们确定这些耦合的非线性，自主振荡器的动力学嵌合态和频率聚类。我们发现，这些动力学状态可以重现我们的数值模型与参数的异质性。此外，我们发现，这个模型是最敏感的外部信号时，准备在同步的开始，嵌合体和集群状态可能会形成。因此，我们提出，在我们的实验系统中的部分同步是一个系统的表现，在同步的边缘与最佳的灵敏度。(C)2021年作者。除非另有说明，否则所有文章内容均根据知识共享署名（CC BY）许可证（http：//creativecommons.org/licenses/by/4.0/）进行许可。
Coupled hair cells of the auditory and vestibular systems perform the crucial task of converting the energy of sound waves and ground-borne vibrations into ionic currents. We mechanically couple groups of living, active hair cells with artificial membranes, thus mimicking in vitro the coupled dynamical system. We identify chimera states and frequency clustering in the dynamics of these coupled nonlinear, autonomous oscillators. We find that these dynamical states can be reproduced by our numerical model with heterogeneity of the parameters. Furthermore, we find that this model is most sensitive to external signals when poised at the onset of synchronization, where chimera and cluster states are likely to form. We, therefore, propose that the partial synchronization in our experimental system is a manifestation of a system poised at the verge of synchronization with optimal sensitivity. (C) 2021 Author(s).
