Resumen de An electric awakening
People with severe brain trauma often fall into a coma. If they "awaken", by showing signs of arousal but not awareness, they are said to be in a vegetative state. This can improve to a state of minimal consciousness, where they might show fluctuating signs of awareness, which come and go, but have no ability to communicate. External stimulation of the brain has been shown to increase arousal, awareness and aspects of cognition in healthy people. Here, Thomson discusses how these people in a vegetative state showed signs of awareness after electric brain stimulation--and minimally conscious people were able to communicate again
