BrainGate2: Feasibility Study of an Intracortical Neural Interface System for Persons With Tetraplegia
The purpose of this study is to obtain preliminary device safety information and demonstrate proof of principle (feasibility of efficacy) of the ability of people with tetraplegia to control a computer cursor and other assistive devices with their thoughts.

Full Study Summary:
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 to recover a host of abilities that normally rely on the hands.
The 4x4 mm BrainGate2 sensor is placed into the motor cortex, connected to a percutaneous pedestal. Neural recordings are made at least weekly for a year or more.
