Table 2. Foci of intervention-related difference in HGO change during auditory processing.

The location, time window, duration, and voxel-wise extent of each cluster of intervention-related difference in stimulus-locked HGO are shown in Table 2. Voxels surviving the spatiotemporal thresholding at p<.005, corresponding to those shown in Figure 2, were tabulated and their associated anatomic labels listed. The voxel location and single time window where the absolute maximal t-value was identified in between-group analyses are listed in the MNI column, with associated t- and p-values to the right. The two right-most columns display the maximum or minimum t-value, as appropriate, obtained from the within-group contrasts in a 1.5 cm³ region around the between-group voxel at either a significance level of p<.005 or p<.05.
