D1 and D2 receptors have been described in different populations of efferent pyramidal neurons of the rat frontal cortex. Combined in situ hybridization and immunocytochemistry show here that these two subtypes are expressed in cortical GABAergic interneurons, with D1 and D2 mainly found in a subpopulation containing parvalbumin, whereas only 10% of the calbindin neurons express D1 receptors. These data indicate that various DA agonists may influence inhibitory circuits by distinct dopamine… CONTINUE READING
