Modulation of evoked responses by stimulation during ON‐ or OFF‐states. (a) Laminar local field potential (LFP) and MUA responses to transcallosal electrical stimulation. Spike occurrences are shown as raster plots. (b,c) Characteristics of MUA and LFP responses, respectively, across cortical layers of M1. *p < 0.05, **p < 0.01, ***p < 0.001. (d,e) Representative examples of stimulation‐evoked MUA and LFP responses, respectively, during ON (top)‐ and OFF (bottom)‐states. (f,g) Example of average stimulation‐evoked MUA and LFPs, respectively, across all channels during ON‐ or OFF‐states (stimulation delivered at time 0). (h,i) Quantification of absolute (left) and normalised (right) stimulation‐evoked spike rates and LFP response, respectively. #0.05 > p < 0.06, ***p < 0.001, paired t‐test
