Table 2. Coordinates of brain activation differences (see Figure 2).
The table shows the maximum z-score, x-y-z coordinates, and brain regions of the peak clusters. Results were thresholded at z>2.3, p<0.05. Pairwise comparison t-tests are related to testing our specific hypotheses, but are limited to regions within the significant F-test results.
