"The key is to reach the largest possible number of configurations allowed by the constraints" #readingToday

Because the brain functions to maintain a predictive model of the environment (the reason the brain evolved is to model the environment, after all), then perhaps the brain's global configuration has to "copy" what is out there: and out there energy distributes in all possible microstates (second principle of thermodynamics). Then to process such variability in nature, the nervous system should have same structure, and the result is the 'inverted U' that has appeared in our analysis and has been theoretically proposed in other publications, the top of the curve representing more possible combinations to handle information/energy exchanges. On the other hand, in the extremes of this curve we find fewer microstates, thus these are not optimal situations to process the many microstates in the environment. The key then, is not to reach the maximum number of units interacting (which would be all-to-all connections and thus only one possible microstate), but rather the largest possible number of configurations allowed by the constraints.
