The direct and indirect striatal pathways form a cornerstone of the circuits of the basal ganglia. Dopamine has opponent affects on the function of these pathways due to the segregation of the D1- and D2-dopamine receptors in the spiny projection neurons giving rise to the direct and indirect pathways. An historical perspective is provided on the discovery of dopamine receptor segregation leading to models of how the direct and indirect affect motor behavior.
直接和间接纹状体通路构成了基底神经节回路的基石。由于直接和间接通路的棘状投射神经元中D1和D2多巴胺受体的分离,多巴胺对这些通路的功能具有相反的影响。本文提供了一个关于多巴胺受体分离发现的历史视角,从而引出直接和间接通路如何影响运动行为的模型。
