GMV gray matter volume, BA Broadmann area, MNI Montreal Neurological Institute, R right, L left

Automated Anatomical Labeling (AAL) software [94] and the Brodmann templates implemented in MRIcroN software (https://www.nitrc.org/plugins/mwiki/index.php/mricron:MainPage) were employed to define Brodmann area
