In the process of ontogenetic development, subjective experience is formed, the neurophysiological basis of which is multiple combinations of functional body systems selected in behavioral acts of interaction with the external environment or internal replay processes. Subjective experience consists of formed concepts (qualiа), which are used by human consciousness in cognitive processes. In the work of Alexander Huth and his colleagues (Huth et al., 2016), using the method of functional magnetic resonance imaging (fMRI), an attempt was made to localize neurosemantic categories that are formed by semantically similar concepts/qualia, and it was shown that the neurosemantic representation of the English language has a wide distribution across the cerebral cortex without obvious signs initially expected left-hemisphere asymmetry. Based on the theory of functional systems by P.K. Anokhin and the ideas of the School of Systemic Psychophysiology (V.B. Shvyrkov, Yu.I. Alexandrov) it can be assumed that neurosemantic representations should have a brain-wide distribution. This was confirmed in this work on the texts of the Russian language using the fMRI method. The individual semantic maps of each subject look similar in terms of brain activity distribution. The localization of neurosemantic clusters was spatially distributed in the gray matter of the cortex, internal structures, and structures of the cerebellum of the brain.
