人类和非人类灵长类动物会跟随各自同类的目光来识别共同感兴趣的物体。人类依靠眼睛注视来达到此目的，而猴子则更喜欢使用头部注视信息。功能性磁共振成像（fMRI）研究描绘了人类颞上沟（STS）中的一个区域，当受试者主动跟随他人的目光注视时，该区域会被特别激活。同样，使用功能磁共振成像，我们在猴子的中部 STS 中识别出了一个对注视跟踪做出反应的类似区域。因此，尽管人类和猴子可能依赖不同的方向线索来引导注意力，但它们似乎部署了相似且可能同源的皮层区域来跟随同种动物的目光。我们的结果支持这样的观点，即眼睛在人类进化中发展出一种新的社会功能，最有可能支持建立在系统发育上古老的 STS 模块上的合作性相互社会互动，用于处理头部线索。
Human and non-human primates follow the gaze of their respective conspecific to identify objects of common interest. Whereas humans rely on eye-gaze for such purposes, monkeys preferentially use head-gaze information. Functional magnetic resonance imaging (fMRI) studies have delineated an area in the human superior temporal sulcus (STS), which is specifically activated when subjects actively follow the eye-gaze of others. Similarly, using fMRI, we have identified an analogous region in the monkey's middle STS responding to gaze following. Hence, although humans and monkeys might rely on different directional cues guiding their attention, they seem to deploy a similar and possibly homologous cortical area to follow the gaze of a conspecific. Our results support the idea that the eyes developed a new social function in human evolution, most likely to support cooperative mutual social interactions building on a phylogenetically old STS module for the processing of head cues.
