[Comparative population analysis of the variability of human neurodynamics and psychodynamics].

A number of characteristics of morphological, neurodynamical, and psychodynamical levels of organization of individual personality was studied in five isolated different ethnical populations and two panmixic ones. The degree of heritability was found to decrease and that of variability to increase with the rise of organization level. Significant interpopulational differences were shown in the mean values of characteristics under study and their dispersions. The results obtained were discussed in connection with peculiarities of genetical and social structures of investigated human populations.
