Behavioral data were analyzed using one- or two-way analysis of variance (ANOVA), followed by Bonferroni’s post hoc test when indicated by significant (σ = 0.05) main effects or interactions. The ANOVAs for the figures depicting percent control data were conducted on the percent change data. The percent change measure was calculated for each individual subject by dividing each individual rat’s score in the experimental group by the mean score of the control group on that same day, and multiplying by 100.
