1. Figure 1. (A) Mean MPPF BPND concentration at basal state in ASD patients group (N = 18), color bar = MPPF BP_ND value. The color bar represents MPPF BP_ND. (B) Bar plot showing between group comparison (HC and patients (ASD)) for BP values at basal state in each region of interest. No statistical differences were found between patients and controls. Error bars indicate SEM.

Figure 2. T-map SPM within subject analysis (baseline vs. spray, P < 0.01, T > 2.41) showing for ROI (comprised in the mask) the effect of OT administration on MPPF BP_ND compared to basal state in HC (left) and in ASD patients (middle, no effects), (A) dorsal raphe nuclei, (B) amygdala, (C) insula, and (D) OFC. (right). Binding potential values for each group (light gray = controls, 12 per treatment group; dark gray = patients, 9 per treatment group) for each condition and each ROI; *indicates a significant difference induced by OT on MPPF BP_ND variation (1-sample t-test P < 0.05). T-maps are projected on the anatomical mean image of each group. Note that in the patients group, while some isolated voxels showed significant differences, there were no significant clusters.
