'''Example:'''
 
# Neuronal avalanches and critical dynamics
 
## are only found in the awake state and disappear under anesthesia (rodent and humans: (1-4)
 
## Capture the resting state in nonhuman primates, human MRI, ECoG (3, 5, 6).
 
## Describe response variability in sensory processing and motor behavior (7).
 
# Here is a short excerpt MINE of a recent summary on avalanches on criticality optimizing numerous aspects of information procesing in the brain:
 
“Decades ago, it was suggested that critical dynamics optimize information transfer in gene-regulation networks(8-11). Since then, the criticality hypothesis(12-21) and alternative models for scale-invariant neuronal organization (e.g. refs.(22-26)} have gained much ground in the field of neuroscience. The functional benefits of critical dynamics for brain function include maximization of mutual information between stimulus input and output(27-31), information capacity (i.e. the number of possible internal states a network can establish)(32-34), stimulus discrimination(35, 36), and the ability of neurons to flexibly change synchronization while maintaining an overall robust degree of phase-locking(37-40), all of which are highly desirable aspects of information processing.
 
 
# The group might be particularly interested in recent papers from our group and Matias Palva’s group on human disease states and/or behavioral performance demonstrating criticality and deviation from criticality in patients taking anti-epileptic drugs (41, 42), in sleep-deprived normal subjects (43, 44), avalanche scaling exponents in the human brain that correlate with behavioral performance (45, 46) as well as deviations from criticality in animal models of schizophrenia (47).
