Note: Columns display peak voxels (followed by any additional local maxima) of regions obtained from random-effects, whole-brain regression analyses that identify regions in which BOLD response was significantly correlated with measures of generosity in the distal analysis (p < 0.01, corrected). Regions listed are those that produced moderate correlations (r > 0.30) with measures of distal generosity across studies. These cross-study correlations refer to the correlation between average BOLD response over all the voxels of the specified region and generosity measures from the alternate study. Thus, for Study 1, the rightmost column displays the correlation between BOLD response and amount of money (first value) and time (second value) donated to the target in Study 2. Similarly, for Study 2, the rightmost column displays the correlation between BOLD response and amount of money donated in Study 1. Coordinates refer to the stereotaxic space of the Montreal Neurological Institute.
