                                  | An experiment showing that paralyzed patients 
                                    can use brain waves to open and close their 
                                    hands via electrodes implanted in their muscles 
                                    is one step toward using electronics to reconnect 
                                    brain and body. The trick will be making the 
                                    connection more natural by tapping directly 
                                    into the brain and finding the subtle signals 
                                    that make shaking hands or picking up a mug 
                                    of coffee unconscious. Full
