Differential Grey Matter Changes in Sensorimotor Cortex Related to Exceptional Fine Motor Skills
Figure 3
Grey matter increases related to frequent, hand-like foot use.
Areas within the sensorimotor ROI (outlined in blue) showing an increase in grey matter values for group T3 when compared to the control subjects [T3 vs TC,C]. Clusters of significant differences are overlaid on the T1-weighted single-subject MNI standard template. (A–D) p<0.05, corrected, and (E) p<0.15, corrected. In T3 subjects, using their feet in a bipedal fashion, increases were more pronounced for the dominant (left) hemisphere as might have been expected from their overall preference for the right foot.
