Homeostatic criticality in neuronal networks

چکیده

In self-organized criticality (SOC) models, as well in standard phase transitions, is only present for vanishing external fields $h \to 0$. Considering that this rarely the case natural systems, such a restriction poses challenge to explanatory power of these models. Besides that, models dissipative systems like earthquakes, forest fires, and neuronal networks, there no true critical behavior, expressed clean laws obeying finite-size scaling, but scenario called "dirty" or quasi-criticality (SOqC). Here, we propose simple homeostatic mechanisms which promote self-organization coupling strengths, gains, firing thresholds networks. We show with an adequate separation timescales strength threshold dynamics, near (SOqC) can be reached sustained even presence significant input. The adapt cancel inputs ($h$ decreases towards zero). Similar proposed couplings local spin cellular automata, could lead applications earthquake, fire, stellar flare, voting, epidemic modeling.

Generic Criticality in Ecological and Neuronal Networks

We investigate the dynamics of two models of biological networks with purely suppressive interactions between the units; species interacting via niche competition and neurons via inhibitory synaptic coupling. In both of these cases, power-law scaling of the density of states with probability arises without any fine-tuning of the model parameters. These results argue against the increasingly pop...

Self-Organized Criticality in Developing Neuronal Networks

Recently evidence has accumulated that many neural networks exhibit self-organized criticality. In this state, activity is similar across temporal scales and this is beneficial with respect to information flow. If subcritical, activity can die out, if supercritical epileptiform patterns may occur. Little is known about how developing networks will reach and stabilize criticality. Here we monito...

Stability of Neuronal Networks with Homeostatic Regulation

Neurons are equipped with homeostatic mechanisms that counteract long-term perturbations of their average activity and thereby keep neurons in a healthy and information-rich operating regime. While homeostasis is believed to be crucial for neural function, a systematic analysis of homeostatic control has largely been lacking. The analysis presented here analyses the necessary conditions for sta...

Supplementary Information: Stability of neuronal networks with homeostatic regulation

Here we 1) derive stability conditions for the network with a non-linear f/I curve, and 2) the tighter stability criterion which be obtained by considering only the slowest mode of the system. Qualitatively, for the 3-dimensional system a criterion exists based on the envelope of the non-linearity. For the full network, the criterion is based on the maximum slope of the non-linearity and this i...

Developing neuronal networks: Self-organized criticality predicts the future

Self-organized criticality emerged in neural activity is one of the key concepts to describe the formation and the function of developing neuronal networks. The relationship between critical dynamics and neural development is both theoretically and experimentally appealing. However, whereas it is well-known that cortical networks exhibit a rich repertoire of activity patterns at different stage...
