Neural representations underlying visual perception of objects and faces

视觉对象在人脑中是如何表现和识别的？我的研究计划旨在回答这个广泛的问题。在过去的40年里，心理物理学、电生理学以及最近的神经成像研究已经破译了视觉处理早期阶段的许多方面。我们现在知道，视觉感知始于将图像分解成它们最基本的属性，如空间频率和方向。对于能够识别复杂视觉对象的视觉处理的后期阶段，我们所知的要少得多。我们建议使用在低水平视觉研究中起作用的方法的等价物来检查涉及不变视觉对象识别的高水平过程。

How are visual objects represented and recognized in the human brain? My research program is targeted to answer this broad question. In the last 40 years, psychophysics, electrophysiology and, more recently, neural imaging studies have deciphered many aspects of the early stages of visual processing. We now know that visual perception starts with a decomposition of images into their most basic properties such as spatial frequency and orientation. A lot less is known about the later stages of visual processing that enable recognition complex visual objects. We propose to use methodological equivalents of approaches that have been instrumental in studies of lower-level vision to examine higher-level processes involving invariant visual object recognition.
