Volumes are given as mm3 and also as a percentage of the ipsilateral parietal lobe in native space (results for MNI space were essentially identical).
PL = parietal lobe, SMG = supramarginal gyrus, AG = angular gyrus, postCG = postcentral gyrus, supPL = superior parietal lobe; GMWM = grey and white matter, GM = grey matter only; CV = coefficient of variation (standard deviation / mean, expressed as a percentage). * = bigger than contralateral (paired t test, * p<0.05, **<0.01)
