We used functional magnetic resonance imaging to demonstrate preserved conscious awareness in a patient fulfilling the criteria for a diagnosis of vegetative state. When asked to imagine playing tennis or moving around her home, the patient activated predicted cortical areas in a manner indistinguishable from that of healthy volunteers.

Recent functional neuroimaging studies have suggested that "islands" of preserved brain function may exist in a small percentage of patients who have been diagnosed as vegetative.

植物状態の人でも正常人と同じようにfunctionalMRIでは局所的に反応する力がある。
