1-(3-Chlorophenyl) piperazine (mCPP) was previously shown to have an anxiogenic-like effect, i.e., it decreased total interaction in a rat social interaction test. Evidence indicated mediation by activation of 5-HT1C receptors with an ED50 of approximately 500 µg/kg IP (Kennett et al. 1989). A comparable effect is now shown on infusing 4 µg of the drug ICV or infusing 0.5 µg into the hippocampus. Both responses were dose dependent. Infusion of 1 µg mCPP into the amygdala had no effect. None of… CONTINUE READING
