Polr of Srrotonrrgic Me-s in Animal Models of Predation

1. A short critical review of the role of serotonin in predatory attack is given. 2. Among factors determining the degree and Wee of psychopharmacological involvement are: species, drug, and dependent behavioral measure chosen as a representative index of predation. 3. One factor which may limit the actual involvement of serotonin is response non-specificity, i.e. the generalized disinhibition of behavior which is present after reductions in brain -levels of this amine. 4. New data are presented concerning response specificity in two models of predation indicating this may pose an actual problem;
