Scientists have discovered that a person in a vegetative state may emit much more brain activity then once thought.

FOX's Colleen Cappon has more in today's "Housecall For Health":

New research shows that those in a vegetative state may be more aware than doctors thought. Scientists at the University of Western Ontario instructed 16 people in a vegetative state to imagine they were making a fist or wiggling their toes, and then measured brain activity with electrodes attached to their scalp.  They found that despite being considered entirely unconscious, there was the same amount of increased activity in their brains as healthy patients that were given the same command.
