Scientists have been able to reach into the mind of a brain-damaged man and communicate with his thoughts. The research, carried out in the UK and Belgium, involved a new brain scanning method. Awareness was detected in three other patients previously diagnosed as being in a vegetative state. The study in the New England Journal of Medicine shows that scans can detect signs of awareness in patients thought to be closed off from the world. Patients in a vegetative state are awake, not in a coma, but have no awareness because of severe brain damage. The scientists used functional magnetic resonance imaging (fMRI) which shows brain activity in real time.
What if those coma patients thought to be beyond help could actually hear what we are saying? Could feel when pushed and prodded? Could respond to doctors, if only they could see the signs? A new group of neuroscientists thinks it has proved we can communicate with these “locked-in” patients – though not everyone believes them
