Metastable oscillatory modes emerge from synchronization in the brain spacetime connectome

Abstract

The mechanisms underlying transient brain rhythms and weekly stable synchronization of distant brain areas and their link with neural activity is still a matter of debate. Here, the authors use a brain network model to study spatio-temporal synchronization dynamics of brain regions and find that there is an optimal regime where spatially and spectrally resolved metastable oscillatory modes, similar to human magnetoencephalography data, emerge.
