Implementation of EEG neurofeedback (EEG-nf) with
simultaneous fMRI requires an accurate removal of EEG-fMRI
artifacts in real time. We describe a simple and safe
modification of a standard MR-compatible EEG cap that
substantially improves signal quality for EEG-nf based
on frontal EEG asymmetry. The modified cap includes two
reference contours for two frontal EEG channels used to
provide EEG-asymmetry-nf. Subtraction of fitted
reference signals provides random-motion and
cardioballistic artifact power suppression by 6...8 dB.
The proposed EEG signal correction should be performed
in real time after the MR artifact removal and prior to
the average cardioballistic artifact subtraction.
