Establishing a Statistical Link between Network Oscillations and Neural Synchrony

LFP phase modulation estimated by the GLM method does not depend on firing rate.
(A,C), In three simulations, we keep λ3(ϕ) = 1 + 0.4cos(ϕ+π) while varying mean firing rates. The SFC method (A) reports three distinct results, while the GLM method (C) showed that the LFP phase modulations are the same. (B, D), Different combinations of firing rate and LFP phase modulation λ3(ϕ) = 1 + a ⋅ cos(ϕ + π) can yield the same SFC (B), while the GLM method can distinguish the differences in LFP phase modulation (D). For each parameter set (a,firing rate), we had 200 runs. The shaded area is the 95% confidence band.
