Ventral striatal dopaminergic defect is associated with hallucinations in Parkinson's disease
<h3>Conclusions</h3><p>Low striatal DAT function may predispose PD patients to VHs, and the regional distribution of the findings suggests a particular role of the ventral striatum. This is in line with non-PD research ...
