Dynamic network interactions among distinct brain rhythms as a hallmark of physiologic state and function

" In this study, we address the fundamental question of how different brain rhythms continuously interact and collectively behave as a network to facilitate distinct physiologic states and integrated physiologic functions. We analyze temporal patterns in the amplitude of brain waves activation, and probe for coordination and synchronous modulation in dominant and nondominant brain rhythms. We demonstrate the presence of robust coupling profiles representing dynamical network interactions among brain rhythms. We discover an entire ensemble (“alphabet”) of key profiles of brain-wave interactions, which are universally observed for different brain areas and across subjects. Moreover, we find that these interaction profiles and the related networks change with transition from one physiologic state to another, and thus, are a unique signature of physiologic state and function." {Credits 1}
