Phase-lags in large scale brain synchronization: Methodological considerations and in-silico analysis
Fig 4
(a) Values of the arcsine function and (b) an example for transformation of ΩΔτ and .
(a) Blue for arcsin(x) ∈ [−π/2, π/2] and red for arcsin(x) ∈ [π/2, 3π/2] in the Cartesian plane. (b) Values of Ωτ1,2 (black) and ΩΔτ and (red), and ΩΔτ* = ΩΔτ ± π and
(blue), which appear due to the summation sin(Ωτ1 + ϕi) + sin(Ωτ2 + ϕi + 2π).
