  • Title: The role of the dorsal and median raphe in the inhibition of muricide.
    Author: Waldbillig RJ.
    Journal: Brain Res; 1979 Jan 12; 160(2):341-6. PubMed ID: 570081.
    Abstract:
    Previous work has implicated the putative neurotransmitter serotonin in the inhibition of muricide. This study examined the possibility that the nuclei of the mesencephalic raphe function differentially in the control of this behavior. The results indicate that radiofrequency lesions confined to the dorsal raphe are sufficient to produce muricide in naturally non-killing rats. Lesions of the median raphe do not produce attack. Evidence is presented that suggests that the region of the tegmentum juxtaposed to the dorsal raphe and central gray contains neural mechanisms necessary for the final behavioral components of the attack sequence.
