为了探索人类后顶叶皮层和颞上沟内的功能系统参与动作感知的程度，我们通过正电子发射断层扫描测量了人类受试者在用点光显示器模拟生物运动感知过程中的大脑代谢活动。实验设计包括在感知目标导向的手部动作、全身运动、物体运动和随机运动时的活动比较。结果表明，目标导向手动作脚本的感知涉及左半球顶叶内沟和颞上沟尾侧的皮层。相比之下，右侧颞上沟的背侧部和邻近的颞叶皮层以及杏仁核等边缘结构参与了对表达性肢体动作所传达的信号的感知。
To explore the extent to which functional systems within the human posterior parietal cortex and the superior temporal sulcus are involved in the perception of action, we measured cerebral metabolic activity in human subjects by positron emission tomography during the perception of simulations of biological motion with point-light displays. The experimental design involved comparisons of activity during the perception of goal-directed hand action, whole body motion, object motion, and random motion. The results demonstrated that the perception of scripts of goal-directed hand action implicates the cortex in the intraparietal sulcus and the caudal part of the superior temporal sulcus, both in the left hemisphere. By contrast, the rostrocaudal part of the right superior temporal sulcus and adjacent temporal cortex, and limbic structures such as the amygdala, are involved in the perception of signs conveyed by expressive body movements.
