| Abstract: | The activity of the pituitary-adrenal system was studied in the Norway rats selected for both maintenance and elimination of the aggressive behavior towards man in the postnatal ontogeny. The selection of the wild rats for domesticated behavior was shown to result in changes of the pituitary-adrenal system formation in the postnatal ontogeny, which is indicated by differences in the dynamics of the adrenals weight as well as of corticosterone content in the blood plasma and in the adrenals both at rest and under stress conditions between the domesticated and aggressive rats. |
