A validation of Emotiv EPOC Flex saline for EEG and ERP research

The saline version of the Emotiv EPOC Flex was found to capture data similar to that of a research-grade EEG system, measure reliable auditory and visual research-quality ERPs, and index SSVEP signatures while being sensitive to changes in alpha oscillations.
