摘要: Abstract : This technical note describes the differences in recording when events happen between several commercially-oriented electroencephalography (EEG) systems. The four systems examined, Emotiv's EPOC, Biosemi's ActiveTwo, Advanced Brain Monitoring's B-Alert X10 and Quasar's prototype represent different approaches to problem of brain activity human subjects. We found that EPOC introduces significantly more error event timing, though this issue is present all Furthermore, we demonstrate with iterative linear regressions number calibration pulses required properly estimate timing system dependent. Therefore, any new EEG acquisition must be tested independently.
