# Paths to self-organized criticality

@article{Dickman2000PathsTS, title={Paths to self-organized criticality}, author={Ronald Dickman and Miguel Angel Mu{\~n}oz and Alessandro Vespignani and Stefano Zapperi}, journal={Brazilian Journal of Physics}, year={2000}, volume={30}, pages={27-41} }

We present a pedagogical introduction to self-organized criticality (SOC), unraveling its connections with nonequilibrium phase transitions. There are several paths from a conventional critical point to SOC. They begin with an absorbing-state phase transition (directed percolation is a familiar example), and impose supervision or driving on the system; two commonly used methods are extremal dynamics, and driving at a rate approaching zero. We illustrate this in sandpiles, where SOC is a…

### Single Neuron Response Fluctuations: A Self‐Organized Criticality Point of View

- Biology
- 2014

Treating a neuron as a heterogeneous ensemble of numerous interacting ion-channel proteins and using statistical mechanics terms, this chapter interprets neuronal response fluctuations and excitability dynamics as reflections of self-organization of the ensemble that resides near a critical point.

It is suggested that neuronal response fluctuations reflect a process that positions the neuron near a transition point that separates excitable and unexcitable phases.

### Self-organization without conservation: Are neuronal avalanches generically critical?

- Physics
- 2010

It is shown that cortical neural networks obeying neural dynamics is dissipative and there is a loading mechanism "charging" progressively the background synaptic strength, which means that unless parameters are fine tuned, their dynamics is either sub- or super-critical, even if the pseudo-critical region is relatively broad.
