To investigate the regulatory effects of somatodendritic D2 receptors on the terminal's extracellular dopamine (DA) concentration, a D2 antagonist (eticlopride) was infused directly into the ventral tegmental area via a microdialysis probe in chloral hydrate-anesthetized rats. Extracellular DA changes in both the nucleus accumbens (N ACC) and the medial(More)
