用脑磁图和脑电图仪记录了8-12岁健康儿童和成人对向前或向后注视面孔(凝视任务)和两幅等亮度马赛克图像(马赛克任务)的事件相关反应。在儿童中，双侧观察到清晰的枕颞部磁场活动(PLM，约140ms)，且与向前凝视时相比，回避注视时右侧PLM波幅增加。这种影响在成年人身上没有观察到。此外，在注视任务中，儿童右侧PLM的来源主要位于推测的人类MT/V5区周围。这些数据表明，作为PLM观察到的早期枕颞部大脑反应是儿童凝视敏感的组成部分。
Event-related responses to a face with forward gaze or averted gaze (gaze task) and two equiluminous mosaic images (mosaic task) were recorded from healthy children aged 8-12 years and adults, using MEG and EEG. In children, a clear occipito-temporal magnetic field activity (Plm, around 140 ms) was observed bilaterally, and the right Plm amplitude was increased when viewing a face with averted gaze compared with that when viewing a face with forward gaze. This effect was not observed in adults. Furthermore, the source for the right Plm in children in the gaze task was mainly located around the putative human MT/V5 area. These data suggest that the early occipito-temporal brain response observed as the Plm is a gaze-sensitive component in children.
