Table 3.
Comparative analysis of power levels distributed on the scalp of healthy controls. Data were based on 16 healthy controls.
| Left scalp (L; μV2) | Right scalp (R; μV2) | L/R ratio | P value | |
|---|---|---|---|---|
| δ | 11.2 ± 0.1 | 11.1 ± 0.1 | 1.0 | >0.05 |
| θ | 7.4 ± 0.1 | 6.8 ± 0.1 | 1.1 | >0.05 |
| α | 20.9 ± 0.3 | 20.7 ± 0.3 | 1.0 | >0.05 |
| β | 8.5 ± 0.1 | 8.6 ± 0.1 | 1.0 | >0.05 |
| γ | 1.8 ± 0.1 | 1.8 ± 0.1 | 1.0 | >0.05 |
Note that comparative analysis of power levels recorded in the left (FP1, F3, F7, C3, T3, F3, T5, and O1) versus right scalps (FP2, F4, F8, C4, T4, F4, T6, and O2). The electrodes at midline (Fz, Cz, and Pz) were excluded from the data analysis.
