Figure 1.

Statistical non-parametric maps (SnPMs) of exact low-resolution brain electromagnetic tomography (eLORETA) of the alpha band comparing pre-rest and post-rest of hand massage (A) and foot massage (B). White blobs indicate increased activity at post-rest for each massage. Images depicting the SnPMs from different perspectives were based on voxel-by-voxel t-values of the differences. Compared with pre-rest for each massage, we observed a significantly increased alpha band in the left insular cortex at post-rest for hand massage (p < 0.05), and the left and right posterior cingulate cortex at post-rest for foot massage (p < 0.05). Structural anatomy is shown in gray scale (L, left; R, right; A, anterior; P, posterior).
