“Phase transition may explain how brain neurons encode information.” April 2nd, 2013.
Article excerpt (with my emphasis): “…the discovery of the phase transition may have implications for diverse areas such as voltages in electrical circuits, prices of commodities in markets, the variables describing the severity of a disease, the time-to-failure of a device, game theory problems, and biological species extinction probabilities, among others.”

Article except: “It currently remains to be seen whether our mechanism will resist the multiple layers of real-world detail separating the abstract equation  from real neurons in a living brain.”
My comment: If all Brownian processes involve random molecular motion, biological species extinction probabilities might result from random molecular motion that leads to deleterious random mutations in genes. However, in the real-world details of my model of systems biology, molecular motion is epigenetically effected by nutrients and by their metabolism to pheromones. Non-random molecular motion is thermodynamically controlled from the bottom up by nutrients, which also results in organism-level thermoregulation from the top down by effects of nutrient metabolism that result in species-specific pheromone production, which controls reproduction.
When you think about how pulses of electricity are translated into thoughts and ideas, take a moment to reconsider scientifically unsubstantiated opinions in the light of evidence that continues to refute “randomness” at any level of investigation in any species from microbes to man. For example, the requirements for nutrient-dependent pheromone-controlled adaptive evolution via ecological, social, neurogenic, and socio-cognitive niche construction continue to become clearer with more examples from biology that refute randomness and mutations theory. What is currently known about the epigenetic effects of olfactory/pheromonal input attests to the fact that construction of our socio-cognitive niche did not somehow randomly occur at the same time pulses of electricity somehow randomly became thoughts.
