Neuronal avalanches of a self-organized neural network with active-neuron-dominant structure
Neuronal avalanches self-organized neural network active-neuron-dominant structure Neurons and Cognition
2012/5/3
Neuronal avalanche is a spontaneous neuronal activity which obeys a power-law distribution of population event sizes with an exponent of -3/2. It has been observed in the superficial layers of cortex ...

Epidemics on a stochastic model of temporal network
Epidemics stochastic model of temporal network Populations and Evolution
2012/5/2
Contacts between individuals serve as pathways where infections may propagate. These contact patterns can be represented by network structures. Static structures have been the common modeling paradigm...
Decorrelation of neural-network activity by inhibitory feedback
Decorrelation of neural-network inhibitory feedback Neurons and Cognition
2012/5/2
Correlations in spike-train ensembles can seriously impair the encoding of information by their spatio-temporal structure. An inevitable source of correlation in finite neural networks is common presy...
