相互凝视可以被描述为一种心理过程，在此过程中，两个人感觉他们的两种思想之间有一种短暂的联系。在猴子身上，大脑颞上皮层的特定细胞群对凝视有反应。这表明大脑可能已经进化出了解释直接眼神交流的机制。这些机制可能取决于特定大脑区域的激活。正电子发射断层扫描被用来测量健康志愿者在分别观看有目光接触、回避凝视和没有凝视的面孔时大脑区域的活动。正如预期的那样，一个已知参与人脸处理的区域被发现在腹侧枕颞区被激活，特别是在右半球。回避凝视和相互凝视引发的血流反应在相似的区域，不同于涉及面部处理的区域。这些区域包括梭状回的枕部、右侧顶叶小叶、右侧颞下回和两个半球的颞中回。这些结果与一个假设是一致的，即眼睛的感知与凝视的方向无关，是由一个分布式网络提供的。然而，没有确凿的证据表明，特定的区域(s)致力于相互注视处理，(C) 1998学术出版社。
Mutual gaze may be described as a psychological process during which two persons have the feeling of a brief link between their two minds. In the monkey, specific cell assemblies in the superior temporal cortex of the brain are responsive to gaze. This suggests that the brain may have evolved mechanisms for interpreting direct eye contact. These mechanisms could depend on the activation of specific brain regions. Positron emission tomography was used to measure activity in brain regions in healthy volunteers while they were looking at faces featuring, respectively, eye contact, averted gaze, or no gaze. As expected a region known to be involved in face processing was found to be activated in the ventral occipito-temporal region, especially in the right hemisphere. Averted gaze and mutual gaze triggered blood flow responses in similar areas which were different from those involved in face processing. These areas included the occipital part of the fusiform gyrus, the right parietal lobule, the right inferior temporal gyrus, and the middle temporal gyrus in both hemispheres. These results are consistent with the hypothesis that perception of eyes regardless of the direction of the gaze is subserved by a distributed network. However, no conclusive evidence was found for specific area(s) devoted to mutual gaze processing, (C) 1998 Academic Press.
