MRI brain

Project Overview

  • Neuro-prosthetic is brain-computer interface to decode brain signals to assist patients with disabilities
  • Application to use brain-derived signals to assist paraplegic patients to move by volitional control signals recorded from the brain


  • Paralyzed patients will be able to move a wheelchair based on decoded brain signals from the motor cortex

Research Objectives

  • Use non-invasive optical imaging to decode movement-related brain signals from motor cortex
  • Use EEG to decode movement-related brain signals from motor cortex
  • Use multi-sensors to derive intentional movement to drive wheelchair/robot to assist patients

Specific Goals

  • Decode oxy- and dexoxy-hemoglobin signals derived from near-infrared optical brain signals
  • Decode intentional movement directions from EEG signals
  • Interface between brain-derived movement signals and navigational robotic/wheelchair control

The Challenge

  • How are movement directions represented by the optical signals recorded in the motor cortex?
  • How to decode the optical signals from multiple optodes that represent movement direction?
  • How to decode the EEG signals from multiple electrodes that represent movement direction?
