Brain Gate: A brain implant to restore memory | Technology | Scoop.it
“In the next few months, highly secretive US military researchers say they will unveil new advances toward developing a brain implant that could one day restore a wounded soldier's memory.”BrainGate™ Company’s unique technology is able to simultaneously sense the electrical activity of many individual neurons. The sensor consists of a silicon array about the size of a baby aspirin that contains one hundred electrodes, each thinner than a human hair. The array is implanted on the surface of the brain. In the BrainGate™ Neural Interface System, the array is implanted in the area of the brain responsible for limb movement. While not currently approved for use, in other future applications, the array may be implanted in areas of the brain responsible for other body processes. While our company is focused on technology innovation and intellectual property, a number of leading academic, governmental, and health organizations are offering our BrainGate technology and related neural interfaces through clinical trials.The human brain is a parallel processing supercomputer with the ability to instantaneously process vast amounts of information. BrainGate's™ technology allows for an extensive amount of electrical activity data to be transmitted from neurons in the brain to computers for analysis. In the current BrainGate™ system, a bundle consisting of one hundred gold wires connects the array to a pedestal which extends through the scalp. The pedestal is connected by an external cable to a set of computers in which the data can be stored for off-line analysis or analyzed in real-time. Signal processing software algorithms analyze the electrical activity of neurons and translate it into control signals for use in various computer-based applications. Intellectual property has been developed and research is underway for a wireless device as well.
