Complete synchronization in coupled Type-I neurons

Nishant Malik, B. Ashok, J. Balakrishnan

摘要:

对于一类通过非线性反馈机制双向耦合的I型神经元系统,讨论了噪声诱导的完全同步问题。对于神经元的输入,我们指出,每个神经元的随机输入的瞬时相位的瞬时频率的变化率完全匹配的情况下,其输出CS的其他。我们的观察结果可以在实际情况中利用,在人工设备中产生完全同步的输出。对于兴奋性兴奋性突触耦合,耦合和噪声强度的同步误差的函数依赖。最后,我们报告了一个观察噪声诱导的CS之间的非相同的神经元耦合双向通过随机非零耦合在一个大的神经元合奏的所有到所有的方式。

英文摘要:

For a system of type-I neurons bidirectionally coupled through a nonlinear feedback mechanism, we discuss the issue of noise-induced complete synchronization (CS). For the inputs to the neurons, we point out that the rate of change of instantaneous frequency with the instantaneous phase of the stochastic inputs to each neuron matches exactly with that for the other in the event of CS of their outputs. Our observation can be exploited in practical situations to produce completely synchronized outputs in artificial devices. For excitatory-excitatory synaptic coupling, a functional dependence for the synchronization error on coupling and noise strengths is obtained. Finally we report an observation of noise-induced CS between non-identical neurons coupled bidirectionally through random non-zero couplings in an all-to- all way in a large neuronal ensemble.
