Visual assessment of hemispheric dominance is denoted with letters if it was not clear left hemisphere dominance: pL probably left, B bilateral, R right, pR probably right, NA not enough active voxels for evaluation. The subjects are presented in the same order as in Table 3. LIs of 1.00 or −1.00 are presented as 1 or −1, respectively, to improve the readability of the table
aSubject is left-handed
bSubject is ambidextrous
