P300 evoked potential is an electroencephalographic (EEG) signal obtained at the central-parietal region of the brain in response to rare or unexpectedevents. In this work, an experiment on the detection of a P-300 rhythmfor potential applications on brain computer interfaces (BCI)using an Adaptive Neuro Fuzzy algorithm (ANFIS) is presented. The P300 evoked potential is obtained from visual stimuli followed by a motor response from the subject. The EEG signals are obtained with a 14 electrodes Emotiv EPOC headset. Preprocessing of the signals includes denoising and blind source separation using an Independent Component Analysis algorithm. The P300 rhythm is detected usingthe discrete wavelet transform (DWT)applied on the preprocessed signal as afeature extractor, and further enteredto the ANFIS system. Experimental results are presented.
