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.
