Optical illusions have broadened our understanding of the brain's role in visual perception. A modern day optical illusion emerged from a posted photo of a striped dress, which some perceived as white and gold and others as blue and black. Here we show, using functional magnetic resonance imaging (fMRI), that those who perceive The Dress as white/gold have higher activation in response to the image of The Dress in brain regions critically involved in higher cognition (frontal and parietal brain areas). These results are consistent with theories of top-down modulation and present a neural signature associated with the differences in perceiving The Dress as white/gold or blue/black. Furthermore the results support recent psychophysiological data on this phenomenon and provide a fundamental building block to study interindividual differences in visual processing.
视觉错觉拓宽了我们对大脑在视觉感知中作用的理解。一种现代的视觉错觉源自一张发布的条纹连衣裙照片，有些人将其视为白色和金色，而另一些人则视为蓝色和黑色。在这里，我们使用功能磁共振成像（fMRI）表明，那些将这条连衣裙视为白色/金色的人，在大脑中与高级认知密切相关的区域（额叶和顶叶脑区）对这条连衣裙的图像有更高的激活反应。这些结果与自上而下调节的理论一致，并呈现出一种与将这条连衣裙视为白色/金色或蓝色/黑色的差异相关的神经特征。此外，这些结果支持了关于这一现象的最新心理生理学数据，并为研究视觉处理中的个体差异提供了一个基本的构建模块。
