Figure 2 MR Images (IMAGE) Radiological Society of North America Caption MR images show reduced regional functional connectivity in, A, Parkinson's disease (PD) patients and, B, exclusively in PD + visual hallucinations (VH) patients. Regional functional connectivity analysis revealed lower functional connectivity in PD + VH as well as PD - VH patients compared with control participants in paracentral and occipital regions (yellow areas in A; P < .05, corrected for multiple comparisons). Functional connectivity in frontal, temporal, and subcortical regions was exclusively lower in patients with PD + VH compared with control participants (red areas in B; P < .05, corrected for multiple comparisons).
