Chronic exposure to Mn results in the development of a neurological disorder known as manganism characterized by neurological deficits resembling that seen in Parkinsonism. Although dopaminergic neurons within the nigrostriatal pathway appear intact, Mn-induced irregularities in DA transmission have been
