There is a wide array of medical uses for microchip implants. One example is using the implants with prosthetics. An RFID chip could be placed on top of the brain to improve movement or functionality of the prosthetic. With the implant, the person would have both input and output capabilities. The downside to the brain implant is that the operation is more invasive. As an alternative, doctors could place an electrode on the limb itself that would act on electrical impulses from the brain. The ope- ration is less invasive, but the electrode would have very limi- ted input capabilities.
Myoelectrical limbs are another possible use of RFID. With a myoelectrical limb, the limb can detect and amplify electrical signals. The limb then deciphers the signals and movements of the muscles to determine how the limb should react. For exam- ple the signals indicate if the limb should move horizontally or vertically, or if the hand should open or close.
A third possibility is to control prosthetic limbs or give com- mands for computers is with electroencephalogram (EEG). Electrodes are placed on many different areas of the brain that are used to sense activity from the brain. When the user is trained they could move the cursor across the screen. With this application, patients have to be trained to control their neu- ral activity to achieve the intended result. With neuroelectro- nic interface chips that are implanted directly onto the top of the brain, the users don’t have to be trained. The chip can trans- late the neural activity into the desired result.
One example of the Neuroelectronic Interface being used is with a paraplegic named John Nagle. “Nagle showed an ability to perform a number of tasks with his mind: control a TV, move a mouse cursor on a screen, and command an artificial hand to open and close grip.” (Chan, 2007, p. 13
