Understanding and responding to other people's actions is fundamental for social interactions. Whereas many studies emphasize the importance of parietal and frontal regions for these abilities, several lines of recent research show that the human lateral occipitotemporal cortex (LOTC) represents varied aspects of action, ranging from perception of tools and bodies and the way they typically move, to understanding the meaning of actions, to performing overt actions. Here, we highlight common themes across these lines of work, which have informed theories related to high-level vision, concepts, social cognition, and apraxia. We propose that patterns of activity in LOTC form representational spaces, the dimensions of which capture perceptual, semantic, and motor knowledge of how actions change the state of the world.
理解和回应他人的行为是社交互动的基础。虽然许多研究强调顶叶和额叶区域对这些能力的重要性，但最近有几条研究线索表明，人类外侧枕颞叶皮层（LOTC）代表了动作的多个方面，从对工具和身体的感知以及它们通常的运动方式，到理解动作的含义，再到执行外显动作。在这里，我们强调了这些研究线索的共同主题，这些主题为与高级视觉、概念、社会认知和失用症相关的理论提供了信息。我们提出，LOTC 中的活动模式形成了表示空间，其维度捕获了关于动作如何改变世界状态的感知、语义和运动知识。
