Inferior temporal cortex (IT) is a key part of the ventral visual pathway implicated in object, face, and scene perception. But how does IT work? Here, I describe an organizational scheme that marries form and function and provides a framework for future research. The scheme consists of a series of stages arranged along the posterior-anterior axis of IT, defined by anatomical connections and functional responses. Each stage comprises a complement of subregions that have a systematic spatial relationship. The organization of each stage is governed by an eccentricity template, and corresponding eccentricity representations across stages are interconnected. Foveal representations take on a role in high-acuity object vision (including face recognition); intermediate representations compute other aspects of object vision such as behavioral valence (using color and surface cues); and peripheral representations encode information about scenes. This multistage, parallel-processing model invokes an innately determined organization refined by visual experience that is consistent with principles of cortical development. The model is also consistent with principles of evolution, which suggest that visual cortex expanded through replication of retinotopic areas. Finally, the model predicts that the most extensively studied network within IT-the face patches-is not unique but rather one manifestation of a canonical set of operations that reveal general principles of how IT works.

下颞叶皮质的组织和操作。

下颞叶皮质(IT)是腹侧视觉通路的关键部分,与物体,面部和场景感知有关。但是,IT如何工作?在这里,我描述了一种结合形式和功能并为未来研究提供框架的组织方案。该方案包括沿IT前后轴排列的一系列阶段,由解剖学连接和功能响应定义。每个阶段都包含具有系统空间关系的子区域的补充。每个阶段的组织都由一个偏心率模板控制,并且各个阶段之间的相应偏心率表示是相互联系的。中央凹表征在高敏物体视觉(包括面部识别)中起作用;中间表示计算对象视觉的其他方面,例如行为价(使用颜色和表面提示);外围表示编码有关场景的信息。这种多阶段,并行处理的模型调用了先天确定的组织,该组织通过与皮层发育原理相一致的视觉体验进行了完善。该模型还与进化原理相一致,进化原理表明视觉皮层通过视网膜局部区域的复制而扩展。最后,该模型预测,IT领域中研究最广泛的网络(面部补丁程序)并不是唯一的,而是一组规范操作的一种体现,它揭示了IT工作原理的一般原理。并行处理模型会调用一个先天确定的组织,该组织通过与皮层发育原理相一致的视觉体验进行完善。该模型还与进化原理相一致,进化原理表明视觉皮层通过视网膜局部区域的复制而扩展。最后,该模型预测,IT领域中研究最广泛的网络(面部补丁程序)并不是唯一的,而是一组规范操作的一种体现,它揭示了IT工作原理的一般原理。并行处理模型会调用一个先天确定的组织,该组织通过与皮层发育原理相一致的视觉体验进行完善。该模型还与进化原理相一致,进化原理表明视觉皮层通过视网膜区域的复制而扩展。最后,该模型预测,IT领域中研究最广泛的网络(面部补丁程序)不是唯一的,而是一组规范操作的一种体现,它揭示了IT工作原理的一般原理。
