Self-organization toward criticality by synaptic plasticity
Self-organized criticality has been proposed to be a universal mechanism for the emergence
of scale-free dynamics in many complex systems, and possibly in the brain. While such …

Drifting assemblies for persistent memory: Neuron transitions and unsupervised compensation
Change is ubiquitous in living beings. In particular, the connectome and neural
representations can change. Nevertheless, behaviors and memories often persist over long …

Homeostatic plasticity and external input shape neural network dynamics
In vitro and in vivo spiking activity clearly differ. Whereas networks in vitro develop strong
bursts separated by periods of very little spiking activity, in vivo cortical networks show …
