[¹¹C]Raclopride binding potential in functionally-defined striatal clusters demonstrating group differences for the contrast of (ANH - CON; Reward - Baseline). T-tests shown here (blue lines) are within-group comparisons of $\Delta {\text{BP}}_{\text{ND}}$ values (Reward - Baseline) and between-group comparisons of ${\text{BP}}_{\text{ND}}$ values (Baseline). In each of these four clusters, there was a significant group × condition interaction, Fs(1,20) > 7.38, ps <.010. This was expected given that ANOVA results are dependent on the cluster-defining contrast. The baseline phase depicted here encompasses the first 42 minutes of scanning, from start of acquisition to start of the reward phase, including both the uptake phase and the neutral task block.
