My current major research focus is on direct control of computers and devices from human brain signals. Working with our collaborators, we have experience with both invasive (implanted) techniques and noninvasive (scalp electrode) techniques. Our immediate goal is to provide people with "locked in syndrome" (completely paralyzed and unable to speak) a means of communication and environmental control. Eventually we hope that we may be able to use the brain signals to restore motion to paralyzed limbs.
