Answer:
Deep brain stimulation works to arouse the thalamus in the case of minimally conscious patients who have suffered brain injury. These are people who still have some brain structures in tact because the damage isn't as sever as those in a vegetative state. Psychologists are now looking to deep brain stimulation in order to arouse the thalamus because it is believed to play a pivotal role in forebrain dysfunction after injury. The forebrain helps us organize and make decisions, so deep brain stimulation is an attempt to reconnect all parts of the brain by stimulating the thalamus; a section that passes all cerebrum information along.
