Is prolactin related to activity and emotional reactivity in rats?
Recent studies have shown different relationships between hormones and personality in humans, including a relationship between prolactin levels and impulsivity. The aim of the present work was to study the relationships between basal levels of prolactin and some measures of activity and emotional reactivity in rats. One of the most consistent results showed a negative correlation between basal prolactin levels and activity. This finding is in line with the serotonergic theories of impulsive behavior and with the effects of dopamine upon activity.
