Reaching success (number of pellets obtained out of 20; mean ± SEM) by control, Mn exposed and Mn exposed + L-DOPA treatment mice in the single-pellet task before and after inhalation and after L-DOPA treatment. Note that the Mn-exposed group is impaired since 8 week and the L-DOPA treatment fully reverses the alterations ( versus control group; between L-DOPA treatment group versus Mn exposed group).
