Figure 2. MG depletion prevents dependence-induced escalation in alcohol intake.
(a) Change in average weekly two bottle choice (2BC) ethanol (EtOH) intake (escalation) between week 4 and baseline. (b) Average weekly 2BC intake after each week of chronic intermittent ethanol (CIE) treatment. (c) Novelty-suppressed feeding test (NSFT) and latency to eat in the open field. (d) NSFT and latency to eat in the home cage. n=12 mice per group, except for the Control Diet/Non-Dep (non-dependent) group in the NSFT (n=9). Data are presented as mean±SEM values; # P<0.05, ## P<0.01, planned orthogonal contrasts.
