我们提出了非线性延迟反馈刺激作为一种有效的desertification技术。该方法相对于系统和刺激参数变化具有令人感兴趣的稳健性。我们证明了其广泛的适用性，将其应用到不同的通用振荡器网络，以及人口的爆发神经元。非线性延迟反馈专门抵消异常的相互作用，从而恢复个别振荡单元的固有频率。然而，非线性延迟反馈使得能够强烈地失谐集体振荡的宏观频率。我们提出非线性延迟反馈刺激用于治疗以异常同步为特征的神经系统疾病。
We present nonlinear delayed feedback stimulation as a technique for effective desynchronization. This method is intriguingly robust with respect to system and stimulation parameter variations. We demonstrate its broad applicability by applying it to different generic oscillator networks as well as to a population of bursting neurons. Nonlinear delayed feedback specifically counteracts abnormal interactions and, thus, restores the natural frequencies of the individual oscillatory units. Nevertheless, nonlinear delayed feedback enables to strongly detune the macroscopic frequency of the collective oscillation. We propose nonlinear delayed feedback stimulation for the therapy of neurological diseases characterized by abnormal synchrony.
