Table 2.
Grand averages of SACCO over all measurements (n = 130) on the left and right forehead across three ISO bands.
| Frequency band | SACCO, left (mean ± SD) |
SACCO, right (mean ± SD) |
Left versus right t-test (P-value) |
Left versus right TOST (PTOST) |
Bilateral average SACCO (mean ± SD) |
|---|---|---|---|---|---|
| Endogenic | 0.013 ± 0.005 | 0.011 ± 0.005 | <0.02 | 0.11 | Left > right |
| Neurogenic | 0.010 ± 0.004 | 0.009 ± 0.003 | <0.04 | 0.08 | Left > right |
| Myogenic | 0.007 ± 0.002 | 0.007 ± 0.002 | 0.72 | <0.001; bilaterally equivalent |
0.007 ± 0.002 |
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.
