GIG-ICA for artifact removal. Individual independent components (ICs) and time courses (TCs) for 1 subject obtained from Individual ICA Artifact Removal Plus Group ICA (IRPG), GIG-ICA, and standard group ICA (GICA). The values in parentheses under each estimated IC are the relevant correlation coefficients between the IC and the ground truth (GT) source. The last row shows related TCs. The correlation values under TCs from left to right correspond with IRPG, GIG-ICA, and GICA, respectively. Note that only the nonartifact ICs/TCs are shown.
