Using magnetoencephalography (MEG), the neural response to scenes was recorded and compared with that to faces. The prominent MEG signals in response to scenes appeared 200-300 ms after the stimulus presentation while those in response to faces appeared between 150 and 200 ms. Source locations of the signals were estimated in the right parahippocampal and parieto-occipital regions with a latency of 300 ms for the scene response, whereas those were estimated in the lingual or fusiform gyri bilaterally with a latency of 160 ms for the face response. These data suggest that both the temporal and parietal regions process scenes, while the occipito-temporal regions process faces, and that scene processing takes a longer time than face processing.
利用脑磁图(MEG)记录了对场景的神经反应,并将其与对面孔的神经反应进行了比较。对场景做出反应的显著MEG信号在刺激呈现后200 - 300毫秒出现,而对面孔做出反应的信号在150至200毫秒之间出现。信号的源位置在右侧海马旁回和顶枕区域估计,场景反应的潜伏期为300毫秒,而对面孔反应的信号源位置在双侧舌回或梭状回估计,潜伏期为160毫秒。这些数据表明,颞叶和顶叶区域都处理场景,而枕颞区域处理面孔,并且场景处理比面孔处理需要更长的时间。
