More research has flaunted a hypoactivity in the mesocortical dopamine pathway, which has been hypothesized to mediate the negative, cognitive, and

    tremor in most of the cases. A significant finding was that there was a increase in tonic neuronal discharge in Globus Pallidus and STN neurons after MPTP treatment. Changes in neuronal activity are consistent with other evidence that shows how losing dopamine results in an increase in transportation through indirect pathway and a decrease in transportation through the indirect pathway. The changes in the basal ganglia could be the cause of the symptoms shown by Parkinson's patients. Reduced tonic activity

From these discoveries, it has been shown that dopamine has a profound impact upon the existence of “reward-seeking behaviors” (Arias-Carrión & Pöppel, 2007, p. 481). A 2006 study done by Mathias Pessiglione and his colleagues demonstrated that subjects given L-DOPA, a precursor to dopamine, were more likely to remember decisions that led to rewards and continue
