1 Microinjection of the D2 agonist quinpirole into the A10 dopamine region blocks amphetamine-, but not cocaine-stimulated motor activity. Dopamine immunoglobulin kappa variable 6D-21 (non-functional) Homo sapiens
2 It is suggested that the different mechanisms of action of cocaine and amphetamine, uptake blocker vs. releaser or longloop vs. shortloop feedback inhibition of A10 dopamine neurons, respectively, may account for the differential effects that quinpirole had in blocking the motor-stimulant response to these psychostimulants.
