Abstract: Brain Gate is a brain implant system developed by the Bio-Tech company Cyber kinetics conjunction with the Department of Neuroscience at Brown University. The device was designed to help those who have lost control of their limbs or other bodily functions such as patients with spinal cord injury. The computer chip, which is implanted into the brain, monitors brain activity in the patient and converts the intention of the user into computer commands. Brain continues to send neural signals required for all voluntary actions even in paralyzed patients but due to spinal cord injuries or some kind of stroke, the relay of signals is disrupted from reaching the corresponding destinations. This Brain Gate Neural Interface system fetches these neural signals through fiber optic cables, feed them to neural signal processing software which uses appropriate decoder algorithms to interpret the brain neural signals and execute the corresponding commands with the help of robotic arms. Currently the chip uses 100 hair-thin electrodes that are targeted to the neurons in specific areas of the brain, for example, the area that controls arm movement. This Brain Gate technology is moving towards passing the neural signals through electrical nerve wires implanted inside human body thus eliminating the use of robots
