Table 1.

Center-of-mass of estimated localizer task responses. The coordinates, spread, and area of the estimated brain responses are provided for the three imaging modalities. FNIRS results from the fMRI-session, MEG-session, and combined results are presented. Coordinates are provided in Talairach space based on the FreeSurfer cortical surface registration.
