As 'vegetative' patients ‘talk’ to scientists, Professor Colin Blakemore assesses the profound implications this has for the sick - and the healthy.
Neuroscientists have used a brain scanner to communicate with a patient in a Persistent Vegetative State. Let’s be clear about what they did. The technique they used, functional Magnetic Resonance Imaging (fMRI), doesn’t record brain activity directly. It detects signals related to changes in the flow of blood within the brain, in response to the local demands of active nerve cells, hungry for oxygen and glucose. Clever computer programs turn such measurements into those now-familiar pictures
Brain scanning is not going to tell us how the brain works - at least not in the kind of detail an engineer would want. But it does provide a window into the previously private world of the human mind. It can at least tell us which parts of the brain are active as a person sees, hears, thinks, remembers, plans and carries out actions.
