In patients in a PVS, the activation was restricted to Brodmann areas 41 and 42 bilaterally. Results In both patients in an MCS and the healthy controls, auditory stimulation activated bilateral superior temporal gyri (Brodmann areas 41, 42, and 22). Methods By means of 15O-radiolabeled water–positron emission tomography, we measured changes in regional cerebral blood flow induced by auditory click stimuli in 5 patients in an MCS, 15 patients in a PVS, and 18 healthy controls. Objective To study auditory processing among patients who are in an MCS, patients who are in a PVS, and healthy control subjects.
