Figure 4

sLoreta and mean ERSPs for test conditions in the right hemisphere. sLoreta solutions for the left mu cluster, shown on a 3D Van Essen template highlighting significantly activated voxels associated by mu components, with mean ERSPs across all test conditions (warm colors indicate ERS whereas cool colors indicate ERD). For each condition, ERSPs display changes from a recorded baseline before stimulus onset (−3000 to −2000 ms before stimulus onset for each trial). The final panel in each row indicates statistical differences within each group across test conditions, while the final panel in each column indicates differences between groups within each test condition (pFDR < 0.05). Note: QD = Quiet Discrimination; ND = Noisy Discrimination; FDR = Corrections for False Discovery Rate; ERSP = Event-related Spectral Perturbations.
