Simulation of delta-alpha PAC dynamics by a coupled oscillator system driven by spontaneous fluctuations.
(A to D) The representative simulated delta-alpha PAC dynamics for an individual with higher attention-related AQ subscores (refer to Fig 4A to 4E). (E to H) Representative dynamics for an individual with lower scores (refer to Fig 4F to 4J). (A, E) Time courses of overlaps (i) and the corresponding labels (ii) among delta-alpha PAC states. (B, F) The trajectory of labeled signals in a plane. (C, G) The corresponding bivariate histograms. (D, H) Surrogate data testing under condition d = 2. Surrogate data testing was applied to the density of points indicated by the red circles in panels C and G and the red lines in panels D and H, and the null hypothesis H0 in condition d = 2 was rejected (D and H). The model showed consistent results with the data analysis, evidence of the dynamic PPC-PAC hypothesis.
