fMRI Scans Reveal Some ‘Vegetative State’ Patients Are Actually Conscious
19th May 2010
In a recent report in the New England Journal of Medicine, researchers from the MRC Cognition and Brain Sciences Unit of the University of Cambridge and the Coma Science Group at the University Hospital of Leige describe their use of fMRI technology to scan the brains of patients diagnosed as being in a persistent vegetative state. Surprisingly, they found that a small proportion of the patients could understand and respond to a series of questions even though they showed no outward signs of consciousness. This finding is sure to rewrite the textbook on defining and diagnosing disorders of consciousness.
