MRI Madness

clipped from www.tomsguide.com A man previously thought to be in a vegetative state has successfully communicated with doctors using an MRI machine. However, one of the patients managed to answer a series of yes or no questions using the MRI machine. Asked a series of six questions (such as, "Is your father's name Thomas?"), the patient was asked to think of one type of imagery for 'yes' and another for 'no.' brain activity on the MRI matched that of a control patient.
