Abstract

Non-invasive electroencephalogram (EEG) based Brain-Computer Interfaces (BCIs), which rely on event related desynchronization (ERD), are often affected
by large fluctuations of their accuracy. We want to overcome this drawback by using simultaneous EEG and functional magnetic imaging (fMRI). The question we are addressing in this work is if ERD is still classifiable in EEG on a single trial basis after the removement of fMRI related artefacts. In a first single participant recording we found the classical ERD distribution and were able to compute a leave-one-out-cross-validation (LOOCV) accuracy of 78%, which is significantly higher than chance level.
