NEUROTRANSMITTER AND ENDOCRINE MODULATION OF AGGRESSIVE-BEHAVIOR AND ITS COMPONENTS IN NORMAL HUMANS

Correlations between aggressiveness and its components and plasma conc entrations of norepinephrine (NE), epinephrine (EPI), testosterone (T) , cortisol (Cort) and prolactin (Prl) were studied in 158 physically a nd psychologically healthy male volunteers, Global aggressiveness, exa mined directly in the probands by the Buss-Durkee Hostility Inventory (BDHI), was not correlated with any of the biochemical parameters inve stigated, but reports by first-degree relatives and spouses showed pos itive correlations between global aggressiveness and NE and T levels. The BDHI scores for 'irritability' and 'resentment' were positively co rrelated with NE, T and Cort.
