Receiver Operating Characteristic (ROC) curves.

ROC curves were computed to estimate the discrimination performance (ability to discriminate between presence vs. absence of stimulation) of each of the different EEG responses identified using across-trial averaging in the time domain (TRI-N1, TRI-P2, OLF-N1, OLF-P2) and across-trial averaging in the time-frequency domain (TRI-TF1, TRI-TF2, TRI-TF3, OLF-TF1, OLF-TF2). The shaded areas represent the 95% confidence interval of the obtained curves.
