Comparison of spatial locations of the potential targets
For each subject, the three potential targets were also compared in terms of spatial distance between one another. The mean distances of RSNM targets and sgACC-derived targets from the structural target were compared using paired t-tests. Inter-individual variances for RSNM targets and sgACC-derived targets were determined using F-tests based on the distance of each target from the mean of all coordinates generated by that method.
