Abstract

An intracerebral microdialysis technique was applied to study the effect of metabotropic glutamate receptor (mGluR) agonist on dopamine release in the striatum of methamphetamine (MAP)-sensitized rats. Rats were treated with MAP (1 mg/kg, i.p.) once daily for 6 consecutive days, followed by it 6-day withdrawal. Perfusion of 0.1 mM (1S,3R)-1-aminocyclopentane-trans-1,3-dicarboxylic acid through a microdialysis probe placed in the striatum enhanced the extracellular dopamine level, and induced stereotyped behavior in MAP-sensitized rats. The enhancement of dopamine release and the stereotyped behavior were attenuated by co-perfusion of 0.4 mM RS-α-methyl-4-carboxyphenyl-glycine, a mGluR antagonist. The present results suggest that mGluRs may be involved in the expression of MAP-induced sensitization.
