Self-organization without conservation: are neuronal avalanches generically critical?
Self-organization without conservation: are neuronal avalanches generically critical?
Recent experiments on cortical neural networks have revealed the existence of well-defined avalanches of electrical activity. Such avalanches have been claimed to be generically scale invariant—i.e. power law distributed—with many exciting implications in neuroscience. Recently, a self-organized model has been proposed by Levina, Herrmann and Geisel to explain this empirical …
