*Maxima 1–16 (values in bold) denote the local maxima of general connectivity increase (based on the EC analysis) located in the cerebellum and brainstem after levodopa administration compared to condition without dopaminergic treatment. The analysis was restricted by mask involving expanded primary motor, premotor, sensorimotor cortex, basal ganglia, thalamus, brainstem, and cerebellum. Selective connectivity increase (based on correlation analysis) for all extra-cerebellar brain structures within the mask with each seed region in the ON as compared to the OFF condition is shown in non-bold values. All seed regions (maxima 1–16) are sorted according to the T-score in descending fashion. x, y, z local maxima of clusters in MNI coordinates derived from the contrast ON vs. OFF condition, T T-score, p uncorrected level of significance; *p < 0.05, **p < 0.01, ***p < 0.001—significance with family-wise error correction at cluster level; AL anterior lobe of the cerebellum, PL posterior lobe of the cerebellum
