Abstract:

The goal of this work is to use electrical microstimulation to provide artificial proprioception for individuals using Brain-Machine Interfaces BMIs, and particular for spinal cord injury. Preliminary results suggest that performance levels with combined artificial feedback and visual feedback exceeds that achievable with visual feedback alone. We have also developed new and powerful schemes to remove the electrical artifacts due microstimulation from the neural recordings used for BMI control. This allows us to move to a much more efficient paradigm with continuous brain read out for BMI control of an external device and write in for artificial sensory feedback from that device.
