Validation of EMOTIV EPOC+ for extracting ERP correlates of emotional face processing

Krzysztof Kotowski, Katarzyna Stapor, Jacek Leski, Marian Kotas Abstract The article presents our proposed adaptation of the commercially available EMOTIV EPOC+ EEG headset for neuroscience research based on event-related brain potentials (ERP). It solves EMOTIV EPOC+ synchronization problems (common to most low-cost systems) by applying our proposed stimuli marking circuit. The second goal was to check the capabilities of our modification in neuroscience experiments on emotional face processing. Results of our experiment show the possibility of measuring small differences in the early posterior negativity (EPN) component between neutral and emotional (angry/happy) stimuli consistently with previous works using research-grade EEG systems.
