Table 1.
Mean ± SD whole-brain modulation index (top two rows) and log-transformed MEG power (bottom two rows; power normalized by 1 fT2 cm− 2 prior to log-transforming) in alpha and beta bands. The numbers within the brackets refer to the number of subjects with Z > 1.96. The last two columns present the result of the group-level lead vs. follow comparison.
| FOLLOW | LEAD | Cohen's dz | p value (paired t test) | |
|---|---|---|---|---|
| Modulation index | ||||
| Alpha | −3.28 ± 0.50 (15) | −3.59 ± 0.49 (12) | 0.84 | 0.0042 |
| Beta | −3.24 ± 0.52 (16) | −3.43 ± 0.49 (15) | 0.70 | 0.014 |
| MEG power, mean ± SD | ||||
| Alpha | 2.73 ± 0.23 | 2.70 ± 0.23 | 0.36 | 0.17 |
| Beta | 2.64 ± 0.15 | 2.62 ± 0.17 | 0.23 | 0.36 |
