Description

Summary

Test the feasibility of using electrocorticography (ECoG) signals to control complex devices for motor and speech control in adults severely affected by neurological disorders.

Official Title

A High-Performance ECoG-based Neural Interface for Communication and Neuroprosthetic Control

Details

ECoG is a type of electrophysiological monitoring that uses electrodes placed directly on the exposed surface of the brain to record electrical activity. With this ECoG-based neural interface, study patients will undergo training and assessment of their ability to control a wearable hand robotic exoskeleton and determine if ECoG brain signals can be used to produce speech.
