Relationship between mousekilling and conspecific aggression in the male rat
In order to investigate the relationships between mousekilling and conspecific aggression, behavioral variables of killer and nonkiller rats were compared in a “resident-intruder” paradigm, in resident as well as in intruder animals. The occurrence of offensive items (offensive sideways, attack) was significantly higher in killer rats when they were residents; their corresponding opponents displayed more defensive behaviors. No significant differ…
Serotonergic inhibition of mouse-killing behaviour in the rat
Interspecific aggression and reactivity in rats
Large depletion of brain 5 HT has been shown to induce mouse-killing behavior in the rat. Selective lesions of the raphe nuclei have been investigated in order to determine whether the various components of the 5 HT system exert some specific control over this aggressive behavior. Electrolytic lesions of the dorsal or the median raphe nucleus do not induce mouse killing, whereas combined lesions of these nuclei elicit this behavior in about 40% o…
Involvement of amygdala in inhibitory control over aggression in the rat
An experimentally produced hyperreactivity facilitates initiation of mouse-killing in rats that did not previously develop any stable inhibition of interspecific aggression. Destruction of the corticomedial amygdala or interruption of the stria terminalis interferes with the development of such an inhibition on the basis of “social” influences, whereas lateral amygdaloid lesions have no effect on mouse-killing.
Interspecific aggressiveness and reactivity in mouse-killing and nonkilling rats
The experiments aimed at uncovering possible correlations between inter-specific aggressiveness and general and emotional responsiveness (appraised by means of the open-field technique) in the rat. Killer rats showed a higher level of emotional responsiveness than nonkillers. Removal of the olfactory bulbs induced an increased reactivity both in the rats which were converted into killers in those whose behavior toward mice remained unchanged. Des…
