最近已经证明，眶额皮层是选择性参与时，新的抽象视觉信息的编码，我们调查是否相同的眶额区将在编码新的人脸被激活。目前的正电子发射断层扫描研究表明，11区在右眶额区，这是直接连接到内侧颞叶，是一个关键的额叶区域选择性激活时，正常人受试者从事编码视觉呈现的面孔。此外，更好的面部识别性能与更大的脑血流量相关，特别是在这个眶额区。
Having demonstrated recently that the orbitofrontal cortex is selectively involved when novel abstract visual information is encoded, we investigated whether the same orbitofrontal area would be activated during the encoding of novel human faces. The present positron emission tomography study demonstrated that area 11 in the right orbitofrontal region, which is directly linked to the medial temporal lobe, is a critical frontal area selectively activated when normal human subjects are engaged in encoding visually presented faces. Furthermore, better face recognition performance correlated with greater cerebral blood flow specifically in this orbitofrontal area.
