. A woman with damage to the inner ear's vestibular system, where the sense of balance resides, feels as if she is in constant free fall. Sitting in a neuroscience lab, she puts a set of electrodes on the surface of her tongue, a wired-up hard hat on her head, and the feel of falling stops. The apparatus connects to a computer to create an external vestibular system, replacing her damaged one by sending the proper signals to her brain via her tongue. After a year of sessions with the device, she no longer needs it: her brain has rewired itself to bypass the damaged vestibular system with a new circuit.
