  1. The table lists peak voxels within significant clusters expressing condition-specific intra-dyad correlations, as revealed by random-effects paired-samples t-tests for each contrast. Coordinates are specified in MNI space (2 mm3 resolution). P-values are given after family-wise error (FWE)-correction.
  2. *Coordinates of the voxel around which a sphere was formed for ROI analysis (see text).
