Simultaneous motor and somatosensory restoration via bidirectional BCI in tetraplegia

Summary

Case study from Battelle/Ohio State University demonstrating a bidirectional BCI restoring both voluntary hand movement and tactile sensation simultaneously in a chronic C4 tetraplegic patient. Motor commands decoded from motor cortex drove a functional electrical stimulation sleeve; touch signals from fingertip sensors were encoded as intracortical microstimulation in somatosensory cortex.
