Distributional pattern of Gαolf proteins in striatal medium spiny neurons (MSNs) that form the basal ganglia circuit. Gαolf proteins are colocalized with DA D1 receptors (D1Rs) in the striatonigral MSNs (D1-cells), and with adenosine A2A receptors (A2ARs) in striatopallidal MSNs expressing DA D2 receptors (D2Rs; D2-cells). The striatonigral and striatopallidal pathways arising from the striosome are omitted in this scheme. ACh, acetylcholine; DA, dopamine; GPe, globus pallidus externa; GPi, globus pallidus interna; MC, motor cortex; PMC, premotor cortex; SNr, substantia nigra pars reticulata; SNc, substantia nigra pars compacta; STN, subthalamic nucleus; VTA, ventral tegmental area.
