2ptD performance linking to iFC_SEMO. (a) Representative coronal slices of statistical maps derived from regression analyses showing changes in whole-brain iFC_SEMO with 2ptD gain as predictor (left), and whole-brain iFC_SEMO after rSS with 2ptD thresholds after rSS as predictor (right). Warm colors on the left-hand slice correspond to a positive correlation between iFC and 2ptD gain, whereas warm colors on the right-hand slice relate to negative correlations between iFC and 2ptD thresholds representing improved discrimination performance. Coordinates refer to y in mm MNI space and neurological convention, and individual clusters are reported at whole brain (k > 10 vx). (b) Whole-brain 3D-render depicting clusters in the vicinity of the SI hand area ROI (yellow). Red voxel refer to increased iFC_SEMO after rSS. Resulting voxel of a regression between iFC_SEMO and 2ptD gain are given in cyan, whereas resulting voxel of a regression between iFC_SEMO and 2ptD thresholds are colored in dark blue. Cluster are reported at (k > 10 vx). Inset at right displays enlarged view of marked region. cs: central sulcus; pcs: postcentral sulcus.
