An MR-safe pneumatic tactile stimulator was developed and tested for automated somatotopic mapping using functional MRI. The device was used in a non-invasive fMRI experiment to perform basic somatotopic mapping on three healthy volunteers. Results from fMRI are consistent with maps of S1 obtained from cortical stimulation studies done in surgical patients, and the technique shows promise for future studies.
