Single Neuron Population Dynamics in Human Speech Motor Cortex for a Speech Prosthesis
Leigh R. Hochberg, MD, PhD.
Summary
The purpose of this study is to obtain preliminary device safety information and demonstrate proof of principle (feasibility) of the ability of people with tetraplegia to control a computer cursor and other assistive devices with their thoughts.
Description
The goal of the BrainGate2 research and development project is to identify the core methods and features for a medical device that could allow people with paralysis, including severe speech impairment, to recover a host of abilities that normally rely on the hands or on speech.
