Abstract:
Using the calculation of coefficients of multiple linear regression of two-dimensional
correlation, we studied the mutual influences (functional connectivity) between the
amplitudes of EEG rhythms in people with mental retardation. Multiple regression equations
were geometrically interpreted using polycyclic multigraphs. As a result of the studies and
calculations, it was found that in mental retardation, the number of regression coefficients of
the two-dimensional correlation is determined to be greater than in the norm. In the sinistrals
control group, the coefficients of multiple regression of two-dimensional correlation were
determined more than in the dextrals control group. In mentally retarded sinistrals, the
number of multiple regression coefficients was determined to be less than in mentally
retarded dextrals, but the number of bivariate correlation coefficients was larger. The resulting increase in correlation coefficients may indicate an increase in tone in sinistrals suffering from
mental retardation compared to dextrals with mental retardation. The mechanism of this
increase in tone is realized by linear functions.
