The r-coef corresponds to the maximum correlation of the cluster and their coordinates are reported in the MNI template. The cluster size is given in mm3. WDRS: Widlöcher Depressive Retardation Scale; MADRS: Montgom ery-Åsberg Depression Rating Scale; STAI-YA: State-Trait Anxiety Inventory; SHAPS: Snaith Hamilton Pleasure Scale, gCC, bCC and sCC: genu, body and splenium of the Corpus Callosum, ACR and SCR: anterior and superior corona radiata, SS: sagittal stratum, PLIC: posterior limb of the internal capsule, PTR: posterior thalamic radiation, SLF: superior longitudinal fasciculus, PTR: posterior thalamic radiation.
