 somatosensory brain-computer interface, BCI, based on sensory imagery, SI, has been shown to be effective in providing a viable alternative for individuals who are unable to achieve adequate BCI control using traditional BCI modalities. This study demonstrated that the SI task induced a contralateral cortical activation, which was consistent with the real tactile stimulation and imagined tactile stimulation. Furthermore, the combination of SI and other BCI modalities, such as motor imagery, may provide new avenues for further improving BCI usage and applicability, especially in those subjects unable to attain adequate BCI control with conventional BCI modalities.
