Add to ORKGDespite all the literature showing that brain-computer interfacing (BCI) is achievable in a research setting, reports of paralyzed people utilizing the proposed systems are few. The performances of the BCI systems must most likely improve before they will move from research and become an assistive tool used by patients in their daily life. The majority of BCIs presented to date have been based on EEG. With the sensors placed outside the skull, this technique suffers from poor spatial resolution and low signal power. These limiting factors can be overcome by instead placing the electrodes on the cortical surface (ECoG). The opportunities for evaluating new ideas with invasive techniques are however very limited since the need for surgery exc...
