Comparison of the functional connectivity of the right caudate nucleus between patients with vascular parkinsonism and controls. Comparison of the functional connectivity of the right caudate nucleus between patients with vascular parkinsonism and controls. Contrast is generated as a 2-tailed t test (scale: t = 0.1–5) with a combination of a voxelwise threshold (uncorrected P < .001) and a cluster-extent threshold (family-wise error rate–corrected P < .05), while controlling for age. Decreased functional connectivity of the right caudate nucleus to the posterior cingulate cortex (MNI coordinates: x = 2, y = −42, z = 36) in the axial (A), sagittal (B), and coronal (C) planes is observed. Functional connectivity of the right caudate nucleus to the posterior cingulate cortex negatively correlates with the number of errors during the Stroop Task (D). V. Dunet et al.
