Multi-level exploration of oscillatory brain networks: from neuronal mechanisms to cognition

尽管最近试图了解大脑网络动力学的研究激增，但远距离大脑区域之间进行局部处理和通信的确切机制仍然知之甚少。大量证据表明，频率特定的大脑节律(即神经元振荡)与宽带活动一起在局部和远程神经元同步中发挥关键作用。然而，我们对大脑如何编码和处理信息的知识是零散的，这一事实阻碍了我们对作用机制的理解，因为可用的神经生物学数据来自于在非常不同的空间和时间观察尺度上处理大脑的研究。

Despite the recent surge in studies attempting to understand brain network dynamics, the precise mechanisms that underlie local processing and communication between distant brain areas are still poorly understood. A large body of evidence suggests that frequency-specific brain rhythms (i.e. neuronal oscillations) alongside broadband activities play a key role in local and long-range neuronal synchronization. However, our understanding of the mechanisms at play is impeded by the fact that our knowledge of how our brain encodes and processes information is fragmented because the available neurobiological data stem from studies that address the brain at very different spatial and temporal observation scales.
