Maximum activation peak summary and contrast estimates of brain regions showing an exponential RS effect and related contrast estimates reflecting percentage BOLD signal change from baseline for the six consecutive performed actions (random-effect group analysis, t-contrast, p<.05 corrected at the cluster level, p<.001 uncorrected, cluster extent threshold of 30 voxels).
