Abstract：
:To test the hypothesis that serotonergic modulation of the effects of phencyclidine (PCP) are due to circuit- rather than receptor-based interactions between glutamatergic and serotonergic systems, multivariate profiles of rat behavior were assessed after treatments with the 5-hydroxytryptamine (5-HT) 5-HT2 receptor antagonist ketanserin (1.0 mg/kg), the 5-HT2 receptor agonist (1(2,5-dimethoxy-4-iodophenyl)-2-aminopropane) (DOI; 0.27 mg/kg), various doses of PCP (0.75 to 10.125 mg/kg), or combinations thereof. Ketanserin blocked all effects of DOI, but reduced the effects of PCP only on locomotion. Depending on the dose, PCP was observed to increase or decrease locomotion and the roughness of the rats' patterns of locomotion. In any case, DOI always increased the activity and decreased the roughness of locomotor paths in PCP-treated rats. Thus, co-administration of DOI and PCP did not yield a shift in the dose-effect curve for either drug, but instead resulted in a new behavioral profile consistent with a circuit-based dynamic interaction.
