Brain regions displaying significant α activity modulations in the low (7–11 Hz) or high (11–15 Hz) α frequency bands in two time windows on baseline contrast in the source level
| 7–11 Hz | Early time window (200–600 ms) | Late time window (600–1000 ms) |
|---|---|---|
| Left and right ↓: Heschl gyrus Inferior, middle, and STG calcarine Cuneus Inferior, middle, and superior occipital gyri Inferior parietal gyrus Postcentral gyrus Precentral gyrus Precuneus Supp. motor area | Left and right ↓: Heschl gyrus Inferior, middle, and STG Inferior parietal gyrus Postcentral gyrus Precentral gyrus Supp. motor area | |
| 11–15 Hz | Early time window (200–600 ms) | Late time window (600–1000 ms) |
| Left and right ↓: Calcarine Cuneus Inferior and middle occipital gyri Inferior and middle temporal gyri | Left and right ↑: Calcarine Cuneus Precuneus Inferior and middle occipital gyri Inferior and middle temporal gyri Inferior and superior parietal gyri |
Up-arrows indicate α synchronization (relative increase in power) while down-arrows indicate α desynchronization (relative decrease in power).
