A key open question in visual neuroscience is how sensory input is combined with higher-level influences (e.g. attentional state). This project aims to address this using neuroimaging techniques combined with sophisticated analysis methods that were recently developed to measure when stimulus-related information is being transferred between different brain regions. These methods will be used to investigate the neural mechanisms underlying two fundamental phenomena in visual perception: feature binding and colour constancy. Understanding the neural mechanisms by which sensory input interacts with attention for these tasks would be a major advance in understanding how interactions between brain regions give rise to our perceptual experiences.

视觉神经科学中一个关键的开放问题是感觉输入如何与更高层次的影响（例如注意力状态）相结合。该项目旨在使用神经成像技术与最近开发的复杂分析方法相结合来解决这个问题，以测量何时刺激相关的信息在不同的大脑区域之间转移。这些方法将被用来研究视觉感知中两个基本现象的神经机制：特征绑定和颜色恒常性。了解感官输入与注意力相互作用的神经机制，对于理解大脑区域之间的相互作用如何产生我们的感知体验，将是一个重大的进步。
