Striatal DA is increased with brief STN stimulation. The selectivity of the response was confirmed by (A.) systemic injection of the DA reuptake inhibitor nomifensine (red line), which resulted in a significant increase in DA oxidation current, compared to (B.) serotonin (fluoxetine) and norepinephrine (desipramine) reuptake inhibitors (blue line) which did not significantly increase the STN stimulation-evoked response.
