Magnetoencephalograms confirm a hemispheric difference in responses to auditory stimuli--verbal stimuli elicit a stronger response in the left temporal lobe.
Nippon Telegraph and Telephone (NTT) has announced that it has obtained magnetoencephalogram (MEG) data showing that the left temporal area of the brain responds more strongly to verbal stimuli (five Japanese vowels) than to five pure tones of different frequencies, and that the right temporal area shows the opposite response. The resulting MEG data were obtained from healthy subjects by using a superconducting interference device (SQUID).
