Precisely controlled electrical stimulus can help the nervous system circumvent areas damaged in a spinal cord injury, and allow brain commands to reach limbs, according to a study by UW Medicine researchers.  

The study, published today in PNAS, was conducted by Steve Perlmutter, UW research associate professor of physiology and biophysics, and colleagues. Their reseach involved a neurochip that recorded electrical signals from muscles and triggered stimulating pulses along the spine.
