Dopamine's action in the caudate and putamen will activate the direct pathway and inhibit the indirect pathway. This will result in a decrease in activity in the globus pallidus internal (GPi). With less activity in the GPi, there will be less inhibition of the thalamus, allowing for more excitation of the cortex and increased movement.
