视觉分类被认为发生在人类腹侧颞叶皮层(VTC),但如何实现这种分类仍然是未知的。在这篇评论中,我们考虑的计算和表示,是必要的分类和研究如何的VTC的微观解剖和宏观解剖布局可能会优化它们,以实现快速和灵活的视觉分类。我们建议,有效的分类是通过组织表示在一个嵌套的空间层次结构中的VTC。这种空间层次结构作为一个神经基础设施的视觉信息在VTC的代表性层次结构,从而使灵活的访问类别信息在几个层次的抽象。
Visual categorization is thought to occur in the human ventral temporal cortex (VTC), but how this categorization is achieved is still largely unknown. In this Review, we consider the computations and representations that are necessary for categorization and examine how the microanatomical and macroanatomical layout of the VTC might optimize them to achieve rapid and flexible visual categorization. We propose that efficient categorization is achieved by organizing representations in a nested spatial hierarchy in the VTC. This spatial hierarchy serves as a neural infrastructure for the representational hierarchy of visual information in the VTC and thereby enables flexible access to category information at several levels of abstraction.
