This document summarizes the development of BrainGate technology, a brain-computer interface system that helps paralyzed patients control devices with their thoughts. It was developed in 2003 at Brown University building on early innovations by Dr. Donald Humphrey. The technology connects the brain directly to a computer, either invasively by implanting electrodes in the brain or non-invasively through scalp sensors. While it provides independence for paralyzed users, limitations include the risks of invasive surgery and slow processing speeds. However, continued research aims to develop smaller wireless versions to further help paralyzed individuals and expand applications in the military.

● To help patients.

3. Development
● Bio-tech company Cyber kinetic’s
● Year 2003
● Brown University
● Early innovations by, Dr. Donald Humphrey of Emory
University.

4. BCI Technology
Brain Computer Interface
Connects brain with
computer.

5. Human Research
● Invasive
● Partially Invasive
● Non-invasive

6. INVASIVE NON-INVASIVE
PARTIALLY
INVASIVE

7. Advantages
● Help Paralyzed people.
● Does’nt need any action or
speech.
● Could be used in military.

8. Disadvantage
Surgery is risky and dangerous.
It is not wireles.
Process of conversation is slow.
Process is very expensive.

9. A boon to the paralyzed
Mathew Nagel the first person to use this technology.
“I can’t put it into words…It will give me a sense of
independence.”

10. Future Scope
Smaller wireless device.
Will help in military
