We recorded magnetoencephalographic (MEG) auditory evoked fields (EF) from the L and R hemispheres of 12 paris of twins, 6 monozygotic (MZ), and 6 dizygotic (DZ) and localized the source of the 100 msec latency EF component termed the M100. M100 sources exhibited greater similarity in location in MZ twin pairs, especially in the L hemisphere. These findings support the hypothesis that the functional location of processing of nonmeaningful unattended auditory stimuli may depend more heavily on left hemisphere structures. Furthermore, genetic effects are evident in these left hemisphere structures and their activity, as is a substantial amount of environmental variance.
我们记录了12对双胞胎（6对同卵双胞胎和6对异卵双胞胎）左右半球的脑磁图（MEG）听觉诱发电场（EF），并对潜伏期为100毫秒的EF成分（称为M100）的来源进行了定位。M100来源在同卵双胞胎对中的位置表现出更大的相似性，尤其是在左半球。这些发现支持了以下假设：对无意义的非注意听觉刺激进行处理的功能位置可能更依赖于左半球结构。此外，遗传效应在这些左半球结构及其活动中很明显，环境差异也很大。
