gLPA-2 decomposition of LFP data. Results from fitting gLPA-2 (K = 2; Equation 4) to LFP data for a time segment where the network is driven by 12.5 Hz oscillatory input in the thalamic relay cells. (A) Comparison of ground-truth LFP (“true” LFP; top) with LPA prediction (middle) with difference shown in bottom panel. (B–E) Estimated contributions from the four laminar components (color plots) with spatial profiles (black:$L_n^1$, red:$L_n^2$) shown left and temporal profiles [green:r_n(t); black:$R_n^1(t)=h^1\otimes r_n$, red:$R_n^2(t)=h^2\otimes r_n$] below. Fitted parameters: Δ₁ = 0.48 ms, τ₁ = 3.85 ms, Δ₂ = 4.80 ms, τ₂ = 4.15 ms.
