Data-driven inference of brain dynamical states from the r-spectrum of correlation matrices
Christopher Gabaldon, Adria Mulero, Rong Wang +6
We present a data-driven framework to characterize large-scale brain dynamical states directly from correlation matrices at the single-subject level. By treating correlation thresh…

Optimal Griffiths Phase in Heterogeneous Human Brain Networks: Brain Criticality Embracing Stability and Flexibility across Individuals
Kejian Wu, Dante R. Chialvo, Changsong Zhou +1
A prominent hypothesis in neuroscience proposes that brains achieve optimal performance by operating near a critical point. However, this framework, which often assumes a universal…
