Does anyone know if the specific dopamine receptors i.e. D1-D5 are in any specific area in the basal ganglia or if they are simply intermingled with eachother. I mean, are the D1 receptors in the internal globus pallidus, or the D4 receptors in the caudate head. I don't know, these are presented just as examples. Hope someone can understand and answer my question. Jacob Drollinger (26,'88)
