'Bionic Reconstruction' Restores Hand Function in 3 Patients

Researchers in Austria say that they've successfully completed "bionic reconstruction" procedures that allow individuals to use their minds to control a prosthetic hand that can engage in complicated motor control activities such as unfastening buttons, picking up coins, and pouring water from a cardboard carton.
