Imagery-trained decoder can generalize to cued movements. (a) ROC curve for all participants (thin line) and averaged across participants (thick line) when the decoder was trained on imagery and tested on cued movement. (b) Paired comparison of average AUC across participants for a decoder tested on cued movement, trained on cued movement and imagery. AUC between decoders trained on cued and imagery were not significantly different and were both significantly higher than chance. (c) Confusion matrix calculated from simulated stimulation according to the implemented stimulation paradigm and averaged across participants for a decoder trained on imagery and tested on cued movement. The mean of TPR and TNR was 59%. Bars in (b) represent mean ± s.d., with each circle representing the average AUC for one participant. The asterisks on the right of each bar represent the results of the one-sample Wilcoxon signed rank test for each decoder’s AUC against chance; ∗ p < 0.05; ∗∗ p < 0.01; ∗∗∗ p < 0.001
