Using high-field (7T) fMRI we have investigated the possibility of using visuospatial attention as a control-method for Brain-Computer-Interfaces. A visual attention localizer task was first used to determine the cortical regions that respond to visual attention. A control signal based on the activation in these regions was subsequently used as real-time feedback to the subjects.
