Superficial slow rhythms are coherent across cortical layers and areas. (a) Coherence as a function of frequency and distance between cortical regions, measured with bipolar ECOG derivations, and averaged across 4 subjects. (b) Coherence as a function of frequency and distance between cortical layers, measured with bipolar laminar derivations. (c) Coherence between specific layers in delta/theta band. Individual subject data is shown in Supplementary Fig. 3B. B-C are grand averages across 16 subjects. Significance by distance, frequency and layer for panels a, b and c is shown in Supplementary Fig. 4.
