Critical-state dynamics has gained widespread interest in neuroscience.It is an attractive framework for understanding variability in neuronal systems, which often exhibit power-law scaling.For example, ongoing neuronal oscillations in the alpha-frequency band exhibit power-law scaling in the burst duration, and in the decay of auto-correlations.Importantly, the meta-stability of systems balancing at this critical edge is computationally beneficial.In this presentation, we will first illustrate with computational models how critical behaviour emerges in oscillating neuronal networks.Then, with the model in mind, we will discuss the mechanisms andfunctional implications of altered scaling behaviour in Alzheimers disease and other brain-related disorders.
