The Quantitative Biology Institute Seminar series presents Dr. Misha Rosenblum discussing” Controlling collective synchrony in oscillatory ensembles by precisely timed pulses” on March 16 at 4 p.m.

Rosenblum is from Universität Potsdam in Germany.

Abstract: We present an efficient technique for the 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.
