Incredible Breakthrough in Biotechnology
Losing a body part is horribly painful and depressing. When you are missing a part of yourself it can make you feel useless. This sometimes happens to men and women in the military and to people who have a crippling accident.
Through the help of biotechnology, these people are given hope in the form of new body parts which are called prosthetics.
Therapy and medicine also makes the restoration as seamless as possible making the person feel that he or she has a real body part.
It is a great success when one is able to move and function using his or her prosthesis.
Researchers placed electrode arrays onto the area of the paralyzed volunteer’s brain that’s responsible for identifying tactile sensations, such as pressure. Arrays were also placed on the volunteer’s motor cortex, which directs body movements. The mechanical hand and the arrays on the motor cortex were connected by wires, allowing him to control the hand’s movements with his thoughts.
The mechanical hand, developed by the Applied Physics Laboratory (APL) at Johns Hopkins University, contains sophisticated torque sensors able to detect when pressure is being applied to any of the fingers. It then can convert the physical “sensations” into electrical signals that were routed by wires to the arrays in the patient’s brain.
