Functional connectivity analysis using the region of interest (ROI) in left S1 (Table 1) revealed a sensory-motor functional network in which preobservation (day 1) functional connectivity predicted day 2 motor learning by observing scores for the learning group. Z-score activation peaks, MNI coordinates, and anatomical labels of the sensory-motor clusters in the identified functional network are shown. L, left; R, right; S1, primary somatosensory cortex; PMd, dorsal premotor cortex; SPL, superior parietal lobule; M1, primary motor cortex.
