III. Passage Completion 10%     The power of telekinesis has always fascinated humankind. Wouldn’t it be cool if you could move objects using just yourthoughts? For Ian Burkhart, paralyzed approximately shoulders down, telekinesis of his own body became a reality throughneural bypass technology that allows him to control his once 1 arm again employing only his thoughts.     At nineteen years old, Ian Burkhart crashed into a sandbar from an ocean wave and broke his neck. His brain still producesthe same functioning nerve impulses, but the signals are 2 from the fifth cervical vertebrae down, preventing any braininstructions from reaching beyond his shoulder and upper arms. This injury 3 Burkhart as quadriplegic, meaning that heis unable to move and sense below his upper limbs and torso.     Paralysis comes with major inconveniences. Among them the lack of independence is the worst. 4 to see howtechnology can help him, Burkhart volunteered to be a test subject for the neural bypass system. Essentially, the neural bypasssystem acts as an external nervous system that translates his brain signals to his forearm whenever Burkhart visualizes an armmovement.     Despite the seemingly simple explanation, the entire process is quite 5 . Burkhart’s brain signals are detected using abrain implant, composed of 96 electrodes that record the electric impulses formed when a certain arm action is visualized.However, the sheer amount of info generated (activity is detected 30,000 times per second) is difficult for computers to 6and figure out a pattern to how Burkhart’s brain signals correspond to which arm movements he visualized. Moreover, since hisbrain produces 1 gigabyte of data every three minutes, a huge cable must be 7 to Burkhart’s skull to transfer the data aswifi or bluetooth signals do not have that capacity. Imagine something that looks like a power cord plugged into the top of yourhead.     After the algorithm decodes what type of arm movement Burkhart intended, electrical pulses are delivered through a skinlevel electronic sleeve containing 130 electrodes worn on his forearm, 8 Burkhart’s arm muscles to move. After fifteenweeks of testing, Burkhart can 9 pick up a bottle and even play Guitar Hero once again.Of course this technology is still in its testing stages. So far, the neural bypass system is not 10 with patients withcontinuously contracted muscles. However, Chad Bouton, a researcher working on the neural bypass system, hopes that, in thefuture, this technology can be utilized conveniently at home for all patients who suffer from paralysis.phppiYL7Y
