In this study we have investigated the potential of using visual attention as a control-method for Brain-Computer-Interfaces (BCI). We show using high-field (7T) fMRI that subjects can control their visuospatial attention and that the BOLD effect is strong enough to base a reliable control-signal on. The strength and location of activation was determined for six subjects. In an additional experiment two of the subjects got real-time feedback based on the activation in the activated regions.
