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

点击翻译按钮获取中文摘要

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.
