Grey matter volume reductions in hallucinating PD patients (PD + VH and PDD + VH) compared to non-hallucinating patients (PD–VH) obtained from a VBM analysis with selected regions of interest. Results are overlapped in a normal TI-weighted image. Clusters in a PPN and b thalamus reach significance at a corrected cluster level (P < 0.05 FWE)
