Figure 3. Compulsive repetitive nose poking in mice exposed to a low TCDD dose (TC-0.6).

Figure 3

(A, B, C) The number of nose pokes per rewarded visit (open triangle) and non-rewarded visit (closed circle): (A) Control, (B) TC-0.6, (C) TC-3.0. Each plotted point indicates the average number of nose pokes per visit made by an individual mouse in a session. (D) Group-averaged numbers of nose pokes throughout the sessions per rewarded visit or non-rewarded visit. Error bars indicate ± S.E.M., n = 8/group. * indicates a significant difference from the Control and TC-3.0 groups (P<0.05, ANOVA, followed by Tukey's post hoc test).
