Figure 2: Statistical nonparametric maps (SnPM) of exact low- resolution brain electromagnetic tomography (eLORETA) of the alpha band comparing the post-hand and post-machine massages. The white color indicates increased activity after the post-hand massage. Images depicting the SnPM from different perspectives are based on voxel-by-voxel t-values of the differences. We found significantly increased alpha band activity in the left anterior cingulate cortex after hand massage (p < 0.05), when compared with after machine massage.
