Criticality in Neural Systems /
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 t...
