This device was invented by E.Miller Professor Lee and colleagues who are experts in neuroscience, physiology, medicine and physical rehabilitation at the Department of Medicine Northwestern University development. It can send the signal directly from the brain to the paralyzed muscles without passing through spinal cord, allowing the muscles can move again.

To understand the mechanism of action between the brain and muscles, Miller and his team implanted electrodes of a machine on monkeys to monitor the electrical signals the brain and muscles. Through track record, the researchers created an algorithm that allows them to interpret the signals and understand patterns associated with muscle activity, or in other words they can understand the relationship between brain and muscle activity.

When conducting experiments on monkeys which have been a temporary paralysis at front elbow. The results showed that the monkey brain signals controls a small electrical current transmitted to the muscles in less than 40 milliseconds, help the monkey get a ball like it was time spent not paralyzed.

The device has been implanted system is called a multi-electrode array, capable of detecting 100 active neurons in the brain. It acts as an interface between brains and computers used to interpret the signals associated with movement of the hand.
Miller said the new bioelectrical brain meter can help people with paralysis to move the hands and other muscles in the body at some point. With this device, one day it could be used to help patients paralyzed by spinal cord injuries perform activities in daily life an increasingly more autonomous.
