Table 1.
Grand averages of SAHbO over all measurements (n = 130) on the left and right forehead across 3 ISO frequency bands.
| Frequency band | SAHbO, left (mean ± SD) |
SAHbO, right (mean ± SD) |
Left versus right t-test (P-value) |
Left versus right TOST (PTOST) |
Bilateral average SAHbO (mean ± SD) |
|---|---|---|---|---|---|
| Endogenic | 0.16 ± 0.08 | 0.15 ± 0.07 | 0.52 | < 0.01; bilaterally equivalent |
0.16 ± 0.07 |
| Neurogenic | 0.09 ± 0.04 | 0.09 ± 0.04 | 0.76 | < 0.01; bilaterally equivalent |
0.09 ± 0.04 |
| Myogenic | 0.05 ± 0.02 | 0.05 ± 0.02 | 0.99 | < 0.01; bilaterally equivalent |
0.05 ± 0.02 |
Note: P-values and PTOST were obtained using paired t-tests and TOST, respectively. See Section B in the Supplementary Material for details on TOST. The bold font marks potential features to characterize the prefrontal ISO of the resting human brain.
