Ma et al. include 72 references yet also fail to cite the following, which also seems relevant. Thermodynamics and signatures of criticality in a network of neurons https://www.pnas.org/content/112/37/11508 https://www.pnas.org/content/112/37/11508 "The activity of a brain—or even a small region of a brain devoted to a particular task—cannot be just the summed activity of many independent neurons. Here we use methods from statistical physics to describe the collective activity in the retina as it responds to complex inputs such as those encountered in the natural environment. We find that the distribution of messages that the retina sends to the brain is very special, mathematically equivalent to the behavior of a material near a critical point in its phase diagram."
