Multiple Sclerosis Clinical Trial

ECoG BMI for Motor and Speech Control

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.

Full Description

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 complex robotic system and to determine if ECoG brain signals can be used to produce speech.
