Results: Across participants, the Emotiv EPOC derived coherence values were generally smaller than those from the Neuroscan data, particularly in delta. Neuroscan recordings were downsampled to 128Hz to match the Emotiv EPOC recordings, and coherence between 25 electrode pairs were computed for each of the traditional frequency bands (delta, theta, alpha, beta), resting condition, and recording device. Method: Sixteen adult participants completed 3 blocks of resting EEG (eyes-closed, eyes-open, eyes-closed) with each recording systems in counterbalanced order across participants. To this end, the present study assessed the equivalence in EEG coherence as recorded by Emotiv EPOC and research-based Compumedics Neuroscan systems. Alternatively, a portable, wireless and easy-to-fit EEG gaming system (Emotiv EPOCĀ®, has been recently manufactured but not validated for use in resting EEG coherence research. However traditional EEG cap fitting and calibration procedures can be extensive and intimidating especially for child and clinical populations. Introduction: Resting electroencephalographic (EEG) coherence provides an index of baseline functional connectivity between regions of the brain and has a variety of important applications in neurocognitive and clinical research.
