OBJECTIVE: Much evidence supports the hypothesis that 5-hydroxytryptamine (5-HT) activation is related to the inhibition of aggression. We examined potentially pro- and anti-aggressive effects of the 5-HT2A/2C receptor agonist on specific brain sites. METHOD: Female Wistar rats on the 7th day postpartum were microinjected with the selective 5-HT2A/2C receptor agonist, alpha-methyl-5-hydroxytryptamine maleate (0.2 to 1.0 µg/0.2 µl) into the central amygdaloid nucleus and median preoptic nucleus. For each brain area studied, the frequency of the behaviors: locomotion, social investigation, lateral threat, attacks (frontal and lateral), and biting the intruder were compared among the various treatments by an Analysis of Variance, followed when...
