“Decades ago, it was suggested that critical dynamics optimize information transfer in gene-regulation networks(8-11). Since then, the criticality hypothesis(12-21) and alternative models for scale-invariant neuronal organization (e.g. refs.(22-26)} have gained much ground in the field of neuroscience. The functional benefits of critical dynamics for brain function include maximization of mutual information between stimulus input and output(27-31), information capacity (i.e. the number of possible internal states a network can establish)(32-34), stimulus discrimination(35, 36), and the ability of neurons to flexibly change synchronization while maintaining an overall robust degree of phase-locking(37-40), all of which are highly desirable aspects of information processing. | “Decades ago, it was suggested that critical dynamics optimize information transfer in gene-regulation networks(8-11).
