Causal interactions stratified by trial type (cue-probe sequence) and trial outcome (correct = corr, error = err). Data are permutation-corrected proportion of significant interactions between neural signals at different levels of scale relative to the total number possible on AX correct (orange), BX correct (light purple), and BX error (dark purple) trials. Significant differences are indicated by * (p < 0.01; permutation test). A, B. Microscale (spike-spike) causal interactions in parietal (A) and prefrontal (B) cortex as a function of trial type and outcome. C, D. Mesoscale (LFP-spike) interactions within parietal (C) and prefrontal (D) cortex as a function of trial type and outcome. E, F. Macroscale (LFP-LFP) interactions in parietal (E) and prefrontal (F) cortex as a function of trial type and outcome. Error bars represent the standard deviation of the permutation distributions.
