Pairs of male Sprague-Dawley rats were administered mescaline, lysergic acid diethylamide (LSD), psilocin, N,N-dimethyltryptamine (DMT), 3,4-dimethoxyphenylethylamine (DMPEA), or 5-hydroxydopamine (5-OHDA) IP prior to being placed in a shock-elicited aggression situation. When foot shock was delivered, controls struck each other with their forepaws, but never engaged in either biting or...
Several measures of aggressive behavior were investigated in three ages (40-50, 90-110, and 180-200 days old) and in three strains (Sprague-Dawley, Wistar, and Long-Evans) of rats before and following the administration of mescaline hydrochloride in a shock-elicited aggression situation. The measures included the number of fights, duration of fighting, latency of fighting, number of bites...
Rats were exposed to a series of targets in a shock induced aggression situation. Control rats fought most with moving targets, such as another normal rat, and did not attack immobile targets, such as a dead rat or a rat model. Rats treated with 15 mg mescaline/kg showed a similar pattern of target control though they bit frequently while controls did not bite. Rats treated with 50 mg/kg...
