✦ Synopsis

Aggressive rats could be differentiated from non-aggressive rats on a lower rate of rearing reactions in the open-field activity, as well as on a weaker aptitude for learning, increasing with the complication of the test. The two groups of rats had comparable activity, and a comparable response to pain. Apomorphine decreased the number of rearing reactions and defecations on open-field activity in the same manner in non-aggressive rats as in aggressive animals. In the usual housing conditions, apomorphine increased similarly locomotor activity in both groups, but in observation cages of "emotional" type, the increase was much more pronounced in aggressive rats than in non-aggressive animals.

Apomorphine (1 mg/kg i.v.) has been found to induce aggressive behaviour in rats. Having studied the influence of several factors viz. auditory stimulus, drug dosage, age, sex, strain, and cage size, an experimental design was adopted. Using this design three populations were distinguished among 152

The apomorphine-induced aggression response of isolated rats was examined. The development of aggressive behaviour in adult rats was enhanced after isolation in cages with wire-netting and especially in cages isolated in opacified Makrolon boxes compared with aggregated rats. Young rats kept isolate
