Abstract
A paradigm more sensitive and specific than the original apomorphine model proposed by Senault was employed to measure intraspecific aggression in the rat. Several behavioral measures provided detailed descriptions of aggressive and nonaggressive behaviors. Several new aggressive responses not previously attributed to apomorphine were noted. Graded doses of apomorphine were administered to determine the qualitative and quantitative dose-response relationships produced by apomorphine on both aggressive and nonaggressive behaviors. Maximum fighting times were obtained at apomorphine doses of 2.5 and 5.0 mg/kg.
