A step forward in the quest for a mobile EEG-designed epoch for psychophysiological studies

Area of Science:

• Neuroscience
• Biomedical Engineering
• Psychophysiology

Background:

• Clinical-grade electroencephalography (EEG) systems are standard but often lack portability.
• Mobile EEG systems offer potential for wider application but require validation against established methods.
• The Emotiv Epoc® is a commercially available mobile EEG device with potential for research.

Purpose of the Study:

• To compare a modified reconfigurable mobile EEG system (M-EMOTIV) with a clinical-grade EEG system (Neuronic MEDICID-05®).
• To validate the accuracy and rationale of recordings from the M-EMOTIV prototype.
• To assess the suitability of the M-EMOTIV for psychophysiological experiments.

Main Methods:

• A modified Emotiv Epoc® (M-EMOTIV) system was used alongside a Neuronic MEDICID-05® system.
• Fifteen healthy participants performed a visual oddball task.
• Electrophysiological data and behavioral responses were recorded simultaneously from both devices.
• Pearson's correlation analysis was employed for comparative assessment.

Main Results:

• A good correlation was found between the M-EMOTIV and the clinical-grade system for electrophysiological measures.
• The modified Emotiv Epoc® demonstrated its ability to suitably record EEG data.
• Simultaneous mobile EEG and behavioral recordings were achieved.

Conclusions:

• The modified Emotiv Epoc® (M-EMOTIV) is a validated alternative for mobile EEG recordings.
• This system supports psychophysiological experiments requiring simultaneous behavioral and EEG data.
• The M-EMOTIV system enhances the feasibility of mobile EEG research.
