Abstract
The effects were studied of 5-hydroxytryptamine (5-HT), 5-hydroxytryptophan (5-HTP) and lysergic acid diethylamide (LSD-25) on aggressive behaviour and spontaneous bioelectrical activity of the optic lobes of the ant, Formica rufa. 5-HT, as well as 5-HTP, decreased the number of ants attacking the beetle but increased mutual aggressiveness. The amplitude of EEG waves of spontaneous bioelectrical activity of the optic lobes was increased by both 5-HT and 5-HTP, but markedly decreased by LSD-25. LSD-25 also decreased the aggressiveness of ants.
