Recurrence quantification analysis detects P300 on single-trial EEG

In the present paper, Recurrence Quantification Analysis was applied to detect event-related potential P300 on single-trial EEG. We demonstrated that the emergence of P300 is associated with EEG complexity increase. Besides, the RQA measure of complexity based on recurrence times quantification is sensitive enough to detect these changes on single-trial EEG.
