Fig. 3: Brain activation to hand movements and ipsilateral and contralateral gFCD.
From: Associations between handedness and brain functional connectivity patterns in children
Overlap between left (Ml) and right (Mr) sensorimotor ROIs and brain activation patterns to the right- and left-hand movements, respectively (a and b). Intra (c) and inter (d) hemispheric global functional connectivity densities (gFCD) mapped on inflated dorsal views of the cerebral surface for 600 right-handers and 600 left-handers, and their statistical differences (t-score). The density plots show the corresponding distributions of handedness index (Eq. 1) computed from measures in the left-hand (Mr) and right-hand (Ml) motor ROIs for L, R, and 600 mixed-handers (M). Statistical model: Two-sample T-test (2-sided). An FDR-corrected threshold PFDR < 0.05 (2-sided) was used to display the statistical maps. Green arrows and black or white line contours highlight the location of the Ml and Mr ROIs from Fig. 2. Source data are provided as a Source Data file.
