Figure 1.
ReHo results are presented in this image. The first row shows averaged data for the ADHD and H groups. Pseudo-colored images (red color scale) are threshold at p<0.01 (corrected for multiple comparisons). The second row presents Mann–Whitney U test comparisons between the images of the two groups, ADHD-H and H-ADHD. These images are threshold at p<0.001 (corrected for multiple comparisons). They show relevant regions of difference between the groups, with the most significant ones highlighted by white arrows.
Figure 2.
A comparison of ICA results between healthy adult subjects and the group of ADHD children.
This figure presents the ten principal ICA networks found in healthy adult humans, as presented by Damoiseaux et al. It compares them with the results from our ICA analysis of the ADHD group. On the left of each panel the results for the ADHD group can be seen and compared with the right panel, where the network obtained by Damoiseaux appears with its corresponding name. Results were thresholded for the ADHD group at Z>3.33, corresponding to p<0.001. Only the Right Memory Function network is presented for simplicity, but a similar Left Memory Function network exists.
Figure 3.
Second-level analysis comparing the ICA results of the H and ADHD groups.
This figure presents four sample regions that were found to be statistically significant (p<0.0001, U-Mann Whitney tests) in the ICA analysis of the H group over the ADHD group. These regions are the left temporal superior lobe (72, 49,45, MNI coordinates) in the Somatosensory network, the right calcarine fissure (33, 33, 43) in the Principal Visual network, the mid-frontal lobe (33, 68, 68 and 54, 68 68) for the Left Memory Function network and the right middle cingulum (45, 45, 58) for the Default network.

Amplitude at low frequency (ALFF).
Here ALFF results with pseudo-colored images (red color scale) are presented. The first row shows averaged data for the ADHD and H groups. Images are threshold to Z>2.58 (p<0.001 corrected for multiple comparisons).
