P300 wave feature extraction: preliminary results

Event related potentials (ERPs) are psychophysiological correlates of neurocognitive functioning that reflect the responses of the brain to changes (events) in the external or internal environment of the organism. ERPs have wide usage for clinical-diagnostic and research purposes. P300 is the most important and the most studied component of the ERP. In this paper, a new method for P300 wave feature extraction from electroencephalogram (EEG) signals is introduced. In this method Mexican hat wavelet coefficients were averaged over different scales. A simple classification method was used to demonstrate the robustness of the developed method to detect the P300 waves
