我们比较了功能磁共振成像（fMRI）和脑磁图（MEG）的映射接受性语言功能。参与者在两种不同的成像环境中执行相同的语言任务。MEG激活特征显示颞上回的双侧活动和颞中回的左侧活动。上级回的双侧活动和颞中回的左侧活动。功能磁共振成像激活曲线显示双侧活动在前额叶，上级颞，颞中，和视觉区。从这两种方式得出的偏侧性系数表明，两种方法对共同活跃的感兴趣区域的一致性较差。两种方法之间的参与者的峰值活动位置也有很大差异。(C)2006 Elsevier B.V.保留所有权利。
We compared functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG) for the mapping of receptive language function. Participants performed the same language task in the two different imaging environments. MEG activation profiles showed prominent bilateral activity in superior temporal gyrus and left-lateralized activity in middle temporal gyrus. fMRI activation profiles revealed bilateral activity in prefrontal, superior temporal, middle temporal, and visual areas. Laterality quotients derived from the two modalities showed poor agreement between the two methods for commonly active regions of interest. Locations of peak activity also varied considerably within participants between the two methods. (C) 2006 Elsevier B.V. All rights reserved.
