Handedness Side and Magnetization Transfer Ratio in the Primary Sensorimotor Cortex Central Sulcus

Table 1

Cortical thickness and MT ratio values are expressed in terms of mean ± standard deviation, evaluated within the ROIs representing the primary sensory motor cortex parcellation, according to the Destrieux atlas. For each ROI, the p-value of the Mann-Whitney U test, performed to assess any significant difference in cortical thickness and MT ratio between left- and right-handers, is reported.
