PREVIOUS studies using magnetoencephalographic (MEG) recordings have r
evealed neuronal populations responding to discrete auditory stimuli i
n 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 c
ortex of the human brain in response to auditory stimuli.
