用精确定时脉冲控制振荡系综的集体同步
Controlling collective synchrony in oscillatory ensembles by precisely timed pulses
摘要：
我们提出了一个有效的技术控制同步在全球耦合合奏脉动行动。我们假设我们可以观察到集体振荡，并且可以同时激发系综的所有元素。我们特别注意尽量减少对系统的干预。关键的想法是只在最敏感的阶段刺激。为了找到这个阶段，我们实现了自适应反馈控制。估计瞬时相位的集体模式的飞行中，我们实现了有效的抑制，每个振荡周期使用几个脉冲。我们讨论了神经科学的结果可能的相关性，即用于脑深部电刺激，用于治疗帕金森病的医疗技术的先进算法的发展。
英文摘要：
We present an efficient technique for control of synchrony in a globally coupled ensemble by pulsatile action. We assume that we can observe the collective oscillation and can stimulate all elements of the ensemble simultaneously. We pay special attention to the minimization of intervention into the system. The key idea is to stimulate only at the most sensitive phase. To find this phase we implement an adaptive feedback control. Estimating the instantaneous phase of the collective mode on the fly, we achieve efficient suppression using a few pulses per oscillatory cycle. We discuss the possible relevance of the results for neuroscience, namely for the development of advanced algorithms for deep brain stimulation, a medical technique used to treat Parkinson's disease.
