While this difference did not reach statistical significance (p = 0.08; Figure 5C ), this obvious trend is consistent with the suggestion that increased ethanol self-administration in the AIE-exposed rats during the initial part of the drinking session may have resulted in a “leveling off” of the BEC by the end of the session such that there was no longer a difference in drinking between the two groups at that time point.
