G-I: Weights for EEG, ECoG, and LFP recordings, respectively, calculated using the reciprocity approach, for a sample of L5 pyramidal cells in the forelimb (compartments represented as circles), hindlimb (compartments represented as triangles, and enclosed in pink box) and upper lip (compartments represented as squares, and enclosed in red box) regions. Electrodes are represented as red circles. Note the varying color scale ranges. J-L: As in G-I, but calculated using the dipole approach
