Definition • BrainGate Neural Interface Device- a ‘brain-computer’ interface that uses internal neural signal sensor and external processors to convert neural signals into an output signal under the users own control.
What It Is • The sensor consists of a tiny chip (smaller than a baby aspirin) with one hundred electrode sensors each thinner than a hair that detect brain cell electrical activity.
Basic Process • The electrode translates brain activity and sends the information to the computer in a format it can understand.
How it Works • BrainGate uses a sensor that is implanted onto the motor cortex of the brain. The device analyzes brain signals then interprets and translated them into cursor movements.
Current Applications • Navigate Internet • Play Computer Games • Turn Lights On and Off • Control Television
Future Applications • Regulating Breathing • Controlling Body Functions
Benefits • can provide paralyzed or motor-impaired patients a mode of communication through the translation of thought into direct computer control. Nagle, a 25-year-old quadriplegic, is the first human fitted with the BrainGate Neural Interface.
“Here we have a research participant who is capable of controlling his environment by thought alone– something we have only found in science fiction so far.” – Surgeon Gerhard Friehs of Brown Medical School From Forbidden Planet 1956
