N2 - Brain-computer interfaces (BCIs) have been employed to provide different patient groups with communication and control that does not require the use of limbs that have been damaged. In this study, we explored BCI-based navigation in three long term amputees. Each participant attempted motor execution with the affected limb, and performed motor execution with the intact limb, while fMRI activity was recorded. Participants attempted, and executed, one of four tasks to direct the movement of an avatar on a monitor. Classification accuracy was very high across both cue-based and free-choice conditions. Results support the use of this fMRI BCI approach for virtual navigation, which could improve BCIs based on fMRI as well as other approaches such as EEG.
