• Sommario/riassunto: Leading authorities in the field review current knowledge of critical behavior in brain function, both experimental and theoretical. The book begins by summarizing experimental evidence for self-organized criticality in the brain. Subsequently, recent breakthroughs in modeling of neuronal circuits to establish self-organized criticality are described. Finally, the importance of critical dynamics for brain function is highlighted.
