Phase synchronization The PLV of the theta frequency band between the ACC and right BA40 showed a highly significant Group effect, F (1, 27) = 14.85, p < 0.001.
Phase synchronization The PLV of the theta frequency band between the ACC and right BA40 showed a highly significant Group effect, F (1, 27) = 14.85, p < 0.001.
Furthermore, central to our hypothesis, a marginally significant Load × Group interaction effect was found, F (2, 27) = 3.1, p = 0.061 (see Figure 3 ).
