Paralyzed Woman Controls Robotic Arm With Her Thoughts

Surgeons had implanted two 4×4-millimeter grids of hair-thin electrodes in her brain to capture signals from regions involved in planning hand and arm movements.
Earlier this year, another research team reported that two tetraplegic patients had learned to grasp and manipulate objects using a brain-machine interface (BMI), as these sophisticated prosthetics are often called. This new study improves on that work by demonstrating even more fluid and natural movements—the best yet performed by a paralyzed human patient using a BMI.
