In particular, this framework posits that social communication symptoms in autism spectrum disorder (ASD) reflect decreased motivation to engage in reciprocal social behaviors throughout the development that results in fewer experiences with social rewards 2. The social motivation hypothesis of autism proposes that functional disruptions in brain circuits supporting social motivation constitute a primary deficit that contributes to social communication impairments 1. PET-fMRI may be a suitable tool to evaluate novel ASD therapeutics targeting the striatal dopamine system. Our findings that ASD is characterized by impaired striatal phasic dopamine release to incentives provide support for the social motivation hypothesis of autism. Within the ASD group, decreased phasic dopamine release in the putamen was related to poorer theory-of-mind skills. Relative to controls, the ASD group demonstrated decreased phasic dopamine release to incentives in the bilateral putamen and left caudate, as well as increased functional connectivity between a PET-derived right putamen seed and the precuneus and insula. Striatal clusters showing significant between-group BP ND differences were used as seeds in whole-brain fMRI general functional connectivity analyses. Using a bolus + infusion protocol with the D2/D3 dopamine receptor antagonist raclopride, voxel-wise binding potential (BP ND) was compared between groups (controls = 12, ASD = 10) in the striatum. Here, we examined striatal functioning during monetary incentive processing in ASD and controls using simultaneous positron emission tomography (PET) and fMRI. Although this hypothesis is supported by functional magnetic resonance imaging (fMRI) studies, no molecular imaging study has evaluated striatal dopamine functioning in response to rewards in ASD. This framework suggests that impaired mesolimbic dopamine function underlies compromised responses to social rewards in ASD.
