本文用头盔形64导脑磁图系统测量了5名正常人的全头部味觉刺激诱发的舌磁场。刺激物为10%葡萄糖和0.3M NaCl溶液和蒸馏水。最突出的峰（N175米）出现在双侧半球的潜伏期为150-210毫秒。N175米源位于使用双偶极子模型在一个球形导电介质的基础上的个人头部尺寸和叠加在磁共振图像。10%葡萄糖和0.3M NaCl刺激的N175 m偶极子位于两个半球的岛盖和岛周区域，但蒸馏水刺激的偶极子不能准确定位。
Magnetic fields evoked by taste stimuli of the human tongue were measured over the whole head using a helmet-shaped 64 channel magnetoencephalography system in five normal subjects. The stimuli were 10% glucose and 0.3 M NaCl solutions and distilled water. The most prominent peak (N175m) appearing over the bilateral hemispheres had a latency of 150–210 ms. The N175m sources were located using a two-dipole model in a spherical conducting medium based on the individual head dimensions and superimposed on magnetic resonance images. The N175m dipoles due to 10% glucose and 0.3 M NaCl stimuli were located at the operculum and circum-insular areas in both hemispheres, but those due to distilled water could not be located accurately.
