Combo mapping improves signal to noise and better matches electrical stimulation results compared to traditional task activation mapping. Group-level receiver operating characteristic (ROC) curves show improved sensitivity and specificity of the new combo mapping approach (red curve) compared to traditional task activation mapping approach (black curve) independent of threshold (A). Averaging across single-subject results shows a significant improvement in signal to noise ratio (SNR) and area under the ROC curve (AUC) for combo mapping compared to traditional task activation mapping (B). * p < 0.01
