Abstract

It is well known that synchronization patterns and coherence have a major role in the functioning of brain networks, both in pathological and in healthy states. In particular, in the perception of sound, one can observe an increase in coherence between the global dynamics in the network and the auditory input. In this perspective article, we show that synchronization scenarios are determined by a fine interplay between network topology, the location of the input, and frequencies of these cortical input signals. To this end, we analyze the influence of an external stimulation in a network of FitzHugh-Nagumo oscillators with empirically measured structural connectivity, and discuss different areas of cortical stimulation, including the auditory cortex.

大脑网络模型中同步与皮层输入的相互作用

众所周知，无论是在病理状态还是在健康状态下，同步模式和一致性在大脑网络的运作中都发挥着重要作用。特别是在感知声音的过程中，我们可以观察到网络中的全局动态与听觉输入之间的一致性增强。在这篇透视文章中，我们展示了同步情景是由网络拓扑结构、输入位置和这些皮层输入信号的频率之间的微妙相互作用决定的。为此，我们分析了外部刺激对具有经验测量结构连接性的菲茨休-纳古莫振荡器网络的影响，并讨论了包括听觉皮层在内的不同皮层刺激区域。

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
