[Features of using the second principle of thermodynamics for describing brain function].
It has been shown that negative production of information entropy at the expense of its normalization change under the influence of neuromediators is specific for the nervous systems and brain. Chemical synapses are calculation elements with a diffusion input to control information entropy normalization. Reproduction stability of the nervous system and brain, and their functioning as well, are determined due to Lyapunov criteria by the maximum of entropy production in combination with minimum for the entropy itself. As far as information in nervous systems is connected with an element of energy normalization that is much greater than the scales of molecular energy of single atoms, physical and information self-organization can simultaneously either correlate or be sufficiently independent, because entropy corresponds to statically unstable point, with its output being natural in different ways. In particular, the brain potentialities are the more, the further it is advanced in its evolution in the sense of entropy increase of its structure, i.e. evolution perfection of mind results from the elementary meaning of the second principle of thermodynamics but in combination of the biochemical peculiarity--the growth of brain is controlled by adrenogens and because of this correlates with productivity.
