Before revision:  Here we review experimental findings of isolated, layered cortex preparations to URLanize towards the four dynamical motifs of up-states, oscillations, neuronal avalanches, and coherence potentials.
After revision:  Here we review experimental findings of isolated, layered cortex preparations to URLanize towards the four dynamical motifs identified in the cortex in vivo: up-states, oscillations, neuronal avalanches, and coherence potentials.
