论文摘要
大脑动力学中关键行为和振荡模式的存在是一个非常有趣的问题。在本文中,我们考虑了一个神经元种群的模型,在该模型中,每个神经元都是由过度阻尼旋转器建模的。我们发现,在外部参数的空间中,存在一些系统显示同步的区域。有趣的是,就在过渡点,雪崩统计数据显示了幂律行为。同样,在小型系统的情况下,(部分)同步和幂律行为可以同时发生。
The presence of both critical behavior and oscillating patterns in brain dynamics is a very interesting issue. In this paper, we consider a model for a neuron population, where each neuron is modeled by an over-damped rotator. We find that in the space of external parameters, there exist some regions that system shows synchronization. Interestingly, just at the transition point, the avalanche statistics show a power-law behavior. Also, in the case of small systems, the (partially) synchronization and power-law behavior can happen at the same time.
