Effets de l�sions de l'hypothalamus et du globus pallidus et d'injections d'apomorphine dans le globus pallidus, le noyau caud�, la substantia nigra et le septum sur le ?comportement d'agressivit� induit par l'apomorphine? chez le rat

Abstract

Intraspecific apomorphine-induced aggressive behavior in the rat was not affected following electrolytic lesions of the ventromedial hypothalamus. Some inhibition of the aggressive behavior was found after lateral lesions and an almost total suppression after destruction of globus pallidus. These results, as well as those following localized injections of apomorphine into the septum, substantia nigra, caudate nucleus, and globus pallidus suggested that the latter anatomical region may be the major site of the action of apomorphine in the behavior studies. The role of acetylcholine is discussed.
