a nPM exposed mice showed decreased food-seeking behavior, with decreased lever presses (p < 0.05, top panel). Decreased lever presses corresponded with decreased pellets earned per session (p < 0.05, middle panel). Efficiency did not change by nPM (bottom panel), defined by the number of pellets earned divided by number of lever presses. b Decreased food-seeking behavior was marginally altered by nPM in the DRL10 schedule, with fewer lever presses (~ p = 0.055, top panel), and fewer pellets earned (p < 0.05, middle panel) for nPM exposure. Efficiency was not altered (bottom panel). c DRL20 did not show nPM effects. Mean ± SEM; repeated-measure ANOVA, *p < 0.05, ~p = 0.055
