Neurologists all over the world are excited to announce that an advancement in brain-controlled prosthetics have encountered a breakthrough. At the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, neurologist have developed prosthetic arms that are controlled by the brain. In recent tests, Les Baugh, from whom lost both arms at the shoulder after an electrical accident as a teenager, reportedly controlled robotic arms with his thoughts, and was able to sense physical sensations. To make this possible scientist injected electrical sensors or electrodes into his brain - 192 needles 1/15 if an inch long. They also remapped the remaining nerves from his missing arms, to allow the brain signals to be sent to the prosthetic.
Part of the electrodes were placed in the sensory cortex which is responsible for identifying physical sensations, like pressure. Other parts of the electrodes were placed on the motor cortex which is the part of the brain that controls body movements. The man could then control the arms movement

From a stick of wood, to now robotic brain controlled prosthetics. Although these inventions look different, they all are similar in the way that they are here to help. Brain controlled prosthetics provide a lot of advantages: like they help all amputees, they provide that feeling of having something there to use to navigate or to use to direct that was once lost, and they allow the person to have no limits, to do activities that they normally couldn 't do if they were limbless. Those advantages are common among all prosthetics. However, brain controlled prosthetics can do those things, and may provide even more advantages, not with just the amputees, but for the world as well. First off, having a prosthetic that is controlled by similar thoughts and movements as a normal limb can reduce the patient 's effort/energy it generates compared to a regular
