ECoG Direct Brain Interface for Individuals With Upper Limb Paralysis

Brief Title

ECoG Direct Brain Interface for Individuals With Upper Limb Paralysis

Official Title

Acute Electrocorticography (ECoG) Direct Brain Interface for Individuals With Upper Limb Paralysis

Brief Summary

      The purpose of this research study is to demonstrate that individuals with upper limb
      paralysis due to spinal cord injury, brachial plexus injury, amyotrophic lateral sclerosis
      and brain stem stroke can successfully achieve direct brain control of assistive devices
      using an electrocorticography (ECoG)-based brain computer interface system.

Detailed Description

      Brain-computer interface (BCI) technology aims to establish a direct link for transmitting
      information between the brain and external devices, offering a natural and rich control
      signal for prosthetic hands or functional electrical stimulators (FES) to re-animate
      paralyzed hands. This study focuses on an ECoG-based BCI system. ECoG measures brain activity
      using electrodes implanted on the surface of the brain. Each participant will undergo testing
      of the ECoG direct brain interface for up to 29 days. Participants will learn to control
      computer cursors, virtual reality environments, and assistive devices such as hand orthoses
      and functional electrical stimulators using neural activity recorded with the ECoG sensor.
