Abstract

Metabotropic glutamate receptor (mGluR) agonist t-ACPD produced concentration-dependent enhancement of NMDA/apamin-induced burst firing and membrane oscillations in dopamine cells, recorded intracellularly from ventral tegmental area in the rat midbrain slice. Such effects were blocked reversibly by mGluR antagonist MCPG, and mimicked by the selective agonist for group I (but not group II and III) mGluRs. Our results point out a selective involvement of group I mGluRs in facilitating burst firing of midbrain dopamine cells.
