The ability to rapidly and accurately recognize visual stimuli represents a significant computational challenge. Yet, despite such complexity, the primate brain manages this task effortlessly. How it does so remains largely a mystery. The study of visual perception and object recognition was once limited to investigations of brain-damaged individuals or lesion experiments in animals. However, in the last 25years, new methodologies, such as functional neuroimaging and advances in electrophysiological approaches, have provided scientists with the opportunity to examine this problem from new perspectives. This review highlights how some of these recent technological advances have contributed to the study of visual processing and where we now stand with respect to our understanding of neural mechanisms underlying object recognition.
快速准确地识别视觉刺激的能力是一项重大的计算挑战。然而，尽管存在如此复杂性，灵长类动物的大脑却能轻松完成这项任务。其实现方式在很大程度上仍是个谜。视觉感知和物体识别的研究曾经局限于对脑损伤个体的调查或动物的损伤实验。然而，在过去25年里，新的方法，如功能神经成像和电生理方法的进展，为科学家们提供了从新的角度研究这个问题的机会。这篇综述重点介绍了这些最新技术进展如何推动了视觉处理的研究，以及在理解物体识别背后的神经机制方面我们目前所处的位置。
