Table 2.
Names, coordinates and volume of the regions identified with HRF differences in this study using pairwise T-tests, along with the T-statistic. Tables are provided for both HRF parameters that showed a group×time interaction effect (response height and time-to-peak) for two comparisons: healthy controls at baseline > OCD pre-treatment, and OCD post-treatment > pre-treatment. Finally, the region which had time-to-peak differences for both the comparisons is shown. The coordinates and T-statistics correspond to the peak voxel within the region cluster.
