Scientists use brain scan to communicate with Canadian in ‘vegetative state’
Courtesy CBC Scott Routley, 39, had no apparent sign of awareness, but was able to communicate with doctors.
A man who suffered a severe brain injury 12 years ago and had no apparent sign of awareness was able to communicate with researchers in London, Ont., through a specialized brain scanner.
Scott Routley, 39 was able to provide answers to simple questions while having his brain activity scanned in a functional MRI. The scanner measures the real-time activity of the brain by tracking the flow of oxygen-rich blood.
Dr. Adrian Owen of the Centre for Brain and Mind at Western University in London, Ont., said they are dealing with patients who are classified as being in a vegetative state who are awake, but seem unaware of who they are or what's around them.
