Manganese or rotenone exposures used in this study do not result in loss of neuronal viability. A, Except for H₂O₂ (1 mM), none of the compounds applied to the neurons in the DCF assay caused loss of neuronal viability under the conditions and in time frame used in the assay. Mean and 95% confidence intervals are shown, n= 6–24. B, The 24-h exposures to manganese or rotenone at the concentrations used in any of the experiments described below do not result in loss of neuronal viability. Means and 95% confidence intervals are shown, n = 3.
