Criticality in large-scale brain fMRI dynamics unveiled by a novel point process analysis.

Criticality in large-scale brain fMRI dynamics unveiled by a novel point process analysis.

Functional magnetic resonance imaging (fMRI) techniques have contributed significantly to our understanding of brain function. Current methods are based on the analysis of gradual and continuous changes in the brain blood oxygenated level dependent (BOLD) signal. Departing from that approach, recen...
