Mechanisms mediating indirect PAC connections (Case I).
A) Three population toy model comprising three neuronal populations labelled as ‘1’, ‘2’, and ‘3’, oscillating in the theta (θ), delta (δ), and gamma (γ) bands. B) PAC involving the phase of theta in population 1 and the amplitude of gamma in population 3 () obtained when varying the connectivity parameters between populations 1 and 2 (Γ12 = 30:4:1000) and between populations 2 and 3 (Γ23 = 30:4:1000). Panels C to R, displays the 16 predictors used in the ten models explored (Table 2). S) Coefficient of determination (R2) for the ten models explored (Table 2). T) Correlation coefficient between the 16 predictors.
