New Apparatus Shows Brain Activity in Vegetative Patients
So a few days ago, a team of Canadian researchers made a breakthrough discovery. They used an electroencephalography (EEG) device to measure electrical activity in vegetative patients’ brains. Basically, the apparatus is attached to a patient’s head and scientists would measure brain activity in response to questions. For example, if a scientist were to ask a patient to move his arm, the region of the brain responsible for such bodily functions would light up. Although only about 20% of the patients revealed positive results, the breakthrough is tremendous. It is really hard to believe that some people who have been in vegetative states for years are actually conscious and fully aware of their surroundings.
