The impact of NMS and WAS on anhedonic behavior. Exposure to NMS had no impact on sucrose preference, however, exposure to WAS increased sucrose preference in both groups over time (p < 0.001, two-way RM ANOVA). Post hoc analyses revealed a significant increase in sucrose preference at 8-day post-WAS in both groups, compared to baseline and/or 1-day post-WAS consumption rates. #p < 0.05 vs. baseline, ‡p < 0.05 vs. 1-day-post WAS; Fishers’s LSD. n = 5–6 per group.
