چکیده

We analyze the delayed feedback approach to suppression of collective synchrony in a population of globally or randomly coupled neurons. In particular, we consider the main factors of imperfection of the control scheme and their influence on the suppression efficiency. Next, with the help of a realistic model of synaptically coupled population of inhibitory and excitatory neurons we demonstrate the potential of the suppression scheme for neurophysiological applications.

Decoupling of oscillatory ensembles by mixed nonlinear delayed feedback

Synchronization processes are of crucial importance for brain function. Well-coordinated synchrony within and between neuronal populations appears to be an important mechanisms for neuronal signaling and information processing. In contrast, pathologically strong synchronization may severely impair brain function. For instance, resting tremor in Parkinson’s disease is caused by a synchronized po...

Neuronal Multistability Induced by Delay

Feedback circuits are important for understanding the emergence of patterns of neural activity. In this contribution we study how a delayed circuit representing a recurrent synaptic connection interferes with neuronal nonlinear dynamics. The neuron is modeled using a Hodgkin-Huxley type model in which the firing pattern depends on subthreshold oscillations, and the feedback is included as a tim...

Effects of Delayed Feedback on Kuramoto Transition

We develop a weakly nonlinear theory of the Kuramoto transition in an ensemble of globally coupled oscillators in presence of additional time-delayed coupling terms. We show that a linear delayed feedback not only controls the transition point, but effectively changes the nonlinear terms near the transition. A purely nonlinear delayed coupling does not effect the transition point, but can reduc...

Feedback suppression of neural synchrony by vanishing stimulation.

We suggest a method for suppression of collective synchrony in an ensemble of all-to-all interacting units. The suppression is achieved by organizing an interaction between the ensemble and a passive oscillator. Technically, this can be easily implemented by a simple feedback scheme. The important feature of our approach is that the feedback signal vanishes as soon as the control is successful....

Delayed feedback control of collective synchrony: an approach to suppression of pathological brain rhythms.

We suggest a method for suppression of synchrony in a globally coupled oscillator network, based on the time-delayed feedback via the mean field. Having in mind possible applications for suppression of pathological rhythms in neural ensembles, we present numerical results for different models of coupled bursting neurons. A theory is developed based on the consideration of the synchronization tr...
