描述了一种新的细胞群，位于猕猴颞叶的上级颞沟（STSa，有时称为STPa）的前部。这些细胞会选择性地对伸手的动作做出反应，但只有当执行动作的智能体被视为专注于伸手的目标位置时才会做出反应。我们描述了如何从STSa内不同细胞群的特性产生这种条件选择性。一个细胞群选择性地对面孔、眼睛注视和身体姿势做出反应，我们认为这些细胞的子集对其他人的注意力方向进行编码。第二细胞群选择性地响应某些方向上的肢体运动（例如，响应于向左的手臂运动而不是等效的腿运动，反之亦然）。对肢体运动敏感的细胞子集的反应由注意力的方向（由执行动作的代理的头部和身体姿势指示）调制。我们的结论是，这种结合分析的注意力和身体动作的方向支持检测的故意行动。(C)北京大学出版社.
A novel population of cells is described, located in the anterior part of the superior temporal sulcus (STSa, sometimes called STPa) of the temporal lobe in the macaque monkey. These cells respond selectively to the sight of reaching but only when the agent performing the action is seen to be attending to the target position of the reaching. We describe how such conditional selectivity can be generated from the properties of distinct cell populations within STSa. One cell population responds selectively to faces, eye gaze, and body posture, and we argue that subsets of these cells code for the direction of attention of others. A second cell population is selectively responsive to limb movement in certain directions (e.g., responding to an arm movement to the left but not to an equivalent leg movement or vice versa). The responses of a subset of cells sensitive to limb movement are modulated by the direction of attention (indicated by head and body posture of the agent performing the action). We conclude that this combined analysis of direction of attention and body movements supports the detection of intentional actions. (C) 2000 Academic Press.
