Abstract: In this article, for the first time in the Russian-language literature, the neurobiological version of Karl Friston’s theory is presented. For the first time, this theory is presented holistically, in detail and logically built within the framework of one article and, as far as possible, adapted for understanding by neuroscientists and neurophysiologists. How Friston applies this theory in practice is discussed. A critical analysis of internal problems and contradictions in Friston’s theory is carried out.

Keywords: free energy principle, Bayesian brain hypothesis, predictive coding, prediction error, observed states, unobserved states.
