Auditory stimuli activate parietal brain regions: a whole-head MEG study.

Previous studies using magnetoencephalographic (MEG) recordings have revealed neuronal populations responding to discrete auditory stimuli in the supratemporal cortex of the human brain. We used the novel whole-head magnetometer (Neuromag-122) to determine whether regions outside the auditory cortex are activated by auditory stimulation as well. In the present study we report evidence for activation of the parietal cortex of the human brain in response to auditory stimuli.
