摘要

大脑如何感知物体并对感知到的物体进行类别的划分,这是视觉认知神经科学研究的重要目标之一。先前的研究证明,当我们看到物体时,大脑腹侧视觉通路能够对看到的物体进行识别并分类,进而使我们在行为上产生针对物体的不同交互方式。本文总结了腹侧视觉通路与物体视觉分类相关的最新研究进展,从物体在视觉皮层中的神经表征和机制等方面阐述了物体生命度与真实大小这两个重要组织维度的研究现状,提供了新的见解,同时指出了进一步研究的方向。

Abstract

How the brain perceives objects and classifies perceived objects is one of the important goals of visual cognitive neuroscience. Previous research has shown that when we see objects, the brain’s ventral visual pathway recognizes and classifies them, leading to different ways of interacting with them. In this paper, we summarize the latest research progress of the ventral visual pathway related to the visual classification of objects. From the perspective of the neural representation of objects and its underlying mechanisms in the visual cortex, we summarize the current research status of the two important organizational dimensions of object animacy and real-world size, provide new insights, and point out the direction of further research.


Key words: object recognition; visual category; animacy; real-world size
