Striatal dopaminergic function and cortical functional connectivity in 22q11.2 deletion syndrome: an integrative multimodal 18F-DOPA PET and magnetic resonance imaging study.

Dopaminergic signalling is critical for regulating large-scale brain network dynamics and is implicated in the pathophysiology of psychotic disorders. 22q11.2 deletion syndrome (22q11DS), a high-penetrance genetic risk factor for schizophrenia, is associated with both dopaminergic alterations and disruptions in functio...
