with Jiri Horacek, MD Table 1: The change of the BOLD fMR signal associated with the trauma (active) blocks visual activation before the PBSP psychotherapy (baseline). The results indicate the higher and lower fMR signal in trauma (active) blocks in comparison with control neutral blocks condition. The p-values for all voxels exceeding the height threshold (T=3,71) and extent threshold of 10 or more voxels (k=10) are lower than 0,005. The statistical significance for the whole model (set-level) indicating the chance of finding this or a greater number of clusters in the search is p = xy. Note: R, right hemisphere; L, left hemisphere; BA, Brodmann’s Area; x, y, z, coordinates of the Talairach space for each maximum; kE, is the number of voxels extended the threshold of 5 or more.

Figure 1: The areas with increased and decreased BOLD fMR signal associated with the trauma (active) blocks visual activation in comparison with control neutral blocks condition in before and after PBSP investigation. Note: R, right hemisphere; L, left hemisphere. 
Table 2: The differences in BOLD fMR signal in investigations before and after PBSP psychotherapy session. The population inference analysis (2nd level) was analyzed by paired the T – test. The p-values for all voxels exceeding the height threshold (T=3,71) and extent threshold of 10 or more voxels (k=10) are lower than 0,005. The statistical significance for the whole model (set-level) indicating the chance of finding this or a greater number of clusters in the search is p = xy. Note: R, right hemisphere; L, left hemisphere; BA, Brodmann’s Area; x, y, z, coordinates of the Talairach space for each maximum; kE, is the number of voxels extended the threshold of 5 or more. |
