The study was divided into two sessions due to the relatively long MRS acquisition time (15 min per voxel) and the duration of the post effects of rTMS (20 min). In one session, the post-rTMS MRS scan was performed in dominant MC. In the other session, the post-rTMS MRS scan was performed in the lentiform nucleus on the same side. Sessions were randomly ordered. The delay between the end of the TMS procedure and the beginning of the post-TMS MRS acquisition varied from 4 to 18 min (session 1: healthy volunteers: 11.0 ± 3.3 min, patients: 12.4 ± 4.1 min, p = 0.3; session 2: healthy volunteers: 10.2 ± 3.7 min, patients: 11.9 ± 2.9 min, p = 0.2).
