摘要: Local anesthesia of the facial epidermis can effect a substantial decrease in shock-elicited fighting paired rats. The present experiments constitute methodological extensions to mouse killing and spontaneous drug-induced social aggression. In first experiment, known mouse-killing rats were given bilateral lidocaine or placebo injections administered under ether anesthesia. Attack kill latencies significantly longer than placebo; all subjects killed placebo, whereas third failed on initial test. On subsequent testing, decreased nonkilling killed. second experiment intense apomorphine-induced conspecific preselected for aggressiveness was markedly reduced following comparative results both are interpreted reference theoretical assertions regarding import sensory information stimulus-bound attack typology central aggression systems.
