面孔将观察者的注意力吸引到对方感兴趣的物体和位置上,从而使两个智能体建立共同注意力。之前的工作在猕猴皮层中描绘了一个皮层“补丁”网络,用于处理面部,最终还提取有关对方注视方向的信息。然而,连接注视方向信息、引导观察者对相关物体的注意力的神经机制仍然难以捉摸。在这里,我们提出了电生理学证据,证明存在独特的“注视跟踪斑”(GFP),其神经元以高度灵活的方式建立这种联系。只有当这种联系与普遍的社会背景相关时,他人的凝视和被凝视选出的物体才会被联系起来。这些神经元的特性使 GFP 成为根据对方注视控制社交互动的关键开关。
Faces attract the observer’s attention toward objects and locations of interest for the other, thereby allowing the two agents to establish joint attention. Previous work has delineated a network of cortical “patches” in the macaque cortex, processing faces, eventually also extracting information on the other’s gaze direction. Yet, the neural mechanism that links information on gaze direction, guiding the observer’s attention to the relevant object, has remained elusive. Here we present electrophysiological evidence for the existence of a distinct “gaze-following patch” (GFP) with neurons that establish this linkage in a highly flexible manner. The other’s gaze and the object, singled out by the gaze, are linked only if this linkage is pertinent within the prevailing social context. The properties of these neurons establish the GFP as a key switch in controlling social interactions based on the other’s gaze.
