Figure 1.
Illustration of functional connections predicted by depression in PD patients. Functional connections predicted by depression while controlling for other neuropsychiatric scales and UPDRS-III are indicated by arrows on a 3D brain template. The significant associations were all positive. The width of the arrows represents the number of functional connections between the regions (see Supplementary Table S2 for the full list of connections). Note, that significant associations were found in the right hemisphere and midline regions. Abbreviations: ACC, anterior cingulate cortex; Hippocampus, hippocampus and parahippocampal gyrus; IFG, inferior frontal gyrus; IPL, inferior parietal lobule; OFC, orbitofrontal cortex; PCC, posterior cingulate cortex; L, left; R, right. P < 0.05, FDR corrected for multiple comparisons.
