abstract = {Functional imaging studies have found differential neural
activation patterns during reward-paradigms in patients with
autism spectrum disorder (ASD) compared to neurotypical
controls. However, publications report conflicting results
on the directionality and location of these aberrant
activations. We here quantitatively summarized relevant fMRI
papers in the field using the anatomical likelihood
estimation (ALE) algorithm. Patients with ASD consistently
showed hypoactivations in the striatum across studies,
mainly in the right putamen and accumbens. These regions are
functionally involved in the processing of rewards and are
enrolled in extensive neural networks involving limbic,
cortical, thalamic and mesencephalic regions. The striatal
hypo-activations found in our ALE meta-analysis, which
pooled over contrasts derived from the included studies on
reward-processing in ASD, highlight the role of the striatum
as a key neural correlate of impaired reward processing in
autism. These changes were present for studies using social
and non-social stimuli alike. The involvement of these
regions in extensive networks associated with the processing
of both positive and negative emotion alike might hint at
broader impairments of emotion processing in the disorder.},
