Comparison of gLPA components with “ground-truth” LFP components from disconnected network. Top panels: Ground-truth LFP (“true-LFP”) from selective synaptic activation by recorded spikes in neurons belonging to a particular laminar population, to an otherwise disconnected network. Middle panels: Corresponding gLPA components. Bottom panels: Difference between ground-truth (top) and gLPA prediction (middle) panels. First column corresponds to layer 2/3 (n = 1), second column to layer 4 (n = 2), third column to layer 5 (n = 3), fourth column to layer 6 (n = 4). (A) Top section of 12 panels corresponds to gLPA-1, (B) middle section to gLPA-2, and (C) bottom section to gLPA-3. Stimulus and time segment correspond to Figures 2–4. The origin of the inversion of the LFP pattern around 540 ms is probably due to afterhyperpolarization of the layer-5 neurons following the spiking (Buzsáki, 1988).
