| Abstract: | L agerspetz , K. Y. H., T irri , R. & L agerspetz , K. M. J. Neurochemical and endocrinological studies of mice selectively bred for aggressiveness. Scand.J. Psychol ., 1968, g, 157–160.—Several neurochemical and endocrinological variables were studied in male albino mice from two strains, selectively bred for aggressiveness and non-aggressiveness. Differences were found in the weight and the serotonin content of the forebrain, in the catecholamine contents of the brain stem and of the adrenal gland as well as in the weight of the testis. The results indicate that mice selectively bred for aggressiveness show physiological signs of higher orthosympathetic activity than the mice selectively bred for non-aggressiveness. |
