A LFP, AMUA, and CSD time courses across channel depth (n = 6 penetrations). The six pairs of lines show preceding burst and omission responses at the 2nd to the 7th electrode going down, the spacing of the electrodes was 200 μm. B Cortical depth profile of omission responses: peak CSD and AMUA amplitudes plotted for stimulus-evoked (solid bars) and omission responses (empty bars) for CSD (dark grey) and AMUA (light grey). Error bars represent SEM across channels. C Cortical depth of the omission response index (see the ‘ Methods’ section) for CSD (dark grey) and AMUA (light grey). Asterisk marks a significant difference between CSD and AMUA (p < 0.05, Bonferroni corrected across cortical depth). Error bars represent SEM across channels. D CSD maps per burst rate, plotted separately for stimulus-evoked and omission responses. Cortical depth as in A
