Abstract
There has been a long controversy concerning whether the amygdala's response to emotional stimuli is automatic or dependent on attentional load. Using magnoencephalography and an advanced beamformer source localization technique, we found that amygdala automaticity was a function of time: while early amygdala responding to emotional stimuli (40-140 ms) was unaffected by attentional load, later amygdala response (280-410 ms), subsequent to frontoparietal cortex activity, was modulated by attentional load.
摘要
关于杏仁核对情绪刺激的反应是自动的还是依赖于注意力负荷，一直存在着长期的争议。使用脑磁图和先进的波束形成器源定位技术，我们发现杏仁核的自动性是时间的函数：虽然早期杏仁核对情绪刺激的反应（40-140ms）不受注意力负荷的影响，但随后的杏仁核反应（280-410ms），在前顶叶皮层活动之后，受注意力负荷的调节。
