Researchers have discovered they can detect conscious awareness in some patients thought to be in a permanent vegetative state using an inexpensive EEG device that measures electrical activity in the brain.
The use of an electroencephalography, or EEG, machine, which can easily be transported to a patient’s bedside, follows an earlier breakthrough employing a functional MRI scanner to determine whether some people in a vegetative state were in fact consciously aware but unable to physically respond to stimuli.
