2. 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.

3. 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.

4. Basic Process • The electrode translates brain activity and sends the information to the computer in a format it can understand.

5. 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.

6. Current Applications • Navigate Internet • Play Computer Games • Turn Lights On and Off • Control Television

7. Future Applications • Regulating Breathing • Controlling Body Functions

8. 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.
