虽然数十年的研究表明，右侧梭状回 (FG) 的一个区域会对面部做出选择性反应，但第二项研究表明，即使在没有面部或其他类似人类的表面特征的情况下，右侧梭状回 (FG) 也会对一系列生命线索做出反应，包括生物运动和目标导向的动作。这些发现提出了一个问题：FG 是否确实对面孔敏感，或者对更抽象的有生命主体类别敏感。目前的研究使用功能磁共振成像来检查 FG 是否以特定类别的方式对所有面孔做出反应，或者 FG 是否对有生命的代理人的面孔特别敏感。动画智能体在这里被定义为具有理性目标导向行动能力的有意智能体。具体来说，我们检查 FG 如何响应一个看起来像有生命的代理但缺乏目标导向的理性行动能力的实体。感兴趣区域分析表明，与无生命实体相比，FG 对有生命实体的激活更强烈，即使有生命实体和无生命实体的表面特征相同。这些结果表明，FG 不会以特定于类别的方式响应所有面孔，而是对实体是否有生命特别敏感。
While decades of research have demonstrated that a region of the right fusiform gyrus (FG) responds selectively to faces, a second line of research suggests that the FG responds to a range of animacy cues, including biological motion and goal-directed actions, even in the absence of faces or other human-like surface features. These findings raise the question of whether the FG is indeed sensitive to faces or to the more abstract category of animate agents. The current study uses fMRI to examine whether the FG responds to all faces in a category-specific way or whether the FG is especially sensitive to the faces ofanimateagents. Animate agents are defined here as intentional agents with the capacity for rational goal-directed actions. Specifically, we examine how the FG responds to an entity that looks like an animate agent but that lacks the capacity for goal-directed rational action. Region-of-interest analyses reveal that the FG activates more strongly to the animate compared with the inanimate entity, even though the surface features of both animate and inanimate entities were identical. These results suggest that the FG does not respond to all faces in a category-specific way, and is instead especially sensitive to whether an entity is animate.
