简介:在蜗的听觉的信号transduction是包含非线性的扩大和自发的otoacoustic排出物的一个活跃过程。当振荡器关门到Hopf分叉,信号transduction包含由全球性联合的毛细胞组成的单个子单元,它能被建模。联合可以向同步导致转变,它接着导致强壮的非线性的回答。在这里学习的模型,子单元的同步转变是不连续的(炸药)当外部刺激不在时。我们显示出那,面对外部刺激,为acoupling,力量稍微比导致爆炸同步的批评价值降低,子单元的反应有更好的频率选择和更大的signal-to-noise比率。从子单元自己一起被联合的生理的观察,我们进一步建议完全的蜗的一个模型,为机关能检测的频率的整体的财务。
