Functional connectivity analyses were performed for the whole-brain using the right sensorimotor cortex as a seed. The degree of the tapping pattern consistency was included as a covariate of interest. The resulted maps were thresholded at p < 0.005 (two-tailed). The inferences were made at the peak-level using family-wise error correction (FWE) over a small volume of interest. Volumes of interest were defined as spheres (r = 10 mm) around center coordinates of the regions of interest within the hand area of the somatomotor cortices (SMC)(*). Clusters that survived a cluster-level extent threshold of p < 0.05 are also reported. Cluster labeling was performed using AAL (84).
