灵长类动物通过眼动序列探索视觉世界。扫视将感兴趣的细节带入中央凹，而注视则稳定图像。在自然视觉期间，社会灵长类动物将目光投向他人的眼睛，以传达自己的情感和意图，并收集有关他人精神状态的信息。直接凝视是面部表情的一个组成部分，它标志着合作或对资源和社会地位的冲突。尽管眼神交流在灵长类动物的行为中非常重要，但人们对支持这些行为的神经基质知之甚少。在这里，我们表明，猴子杏仁核含有神经元，选择性地回应注视他人的眼睛和目光接触。这些“眼细胞”与猴子杏仁核中的典型视觉反应神经元有几个特征，然而，它们只有在眼睛落在观众的中央凹内时才会对眼睛做出反应，要么是故意扫视的结果，要么是眼睛在注视期间移动到观众的中央凹内，以探索不同的特征。眼睛在周边视觉中的存在不能激活眼睛细胞。这些发现将灵长类动物的杏仁核与眼睛运动联系起来，这些眼睛运动涉及对包含社会和情感显著特征的视觉场景中的细节的探索和选择。
Primates explore the visual world through eye-movement sequences. Saccades bring details of interest into the fovea while fixations stabilize the image. During natural vision, social primates direct their gaze at the eyes of others to communicate their own emotions and intentions and to gather information about the mental states of others. Direct gaze is an integral part of facial expressions that signals cooperation or conflict over resources and social status. Despite the great importance of making and breaking eye contact in the behavioral repertoire of primates, little is known about the neural substrates that support these behaviors. Here we show that the monkey amygdala contains neurons that respond selectively to fixations at the eyes of others and to eye contact. These “eye cells” share several features with the canonical, visually responsive neurons in the monkey amygdala, however, they respond to the eyes only when they fall within the fovea of the viewer, either as a result of a deliberate saccade, or as eyes move into the fovea of the viewer during a fixation intended to explore a different feature. The presence of eyes in peripheral vision fails to activate the eye cells. These findings link the primate amygdala to eye-movements involved in the exploration and selection of details in visual scenes that contain socially and emotionally salient features.
