Understanding the neural dynamics of colour constancy and feature binding

视觉神经科学中一个关键的悬而未决的问题是，感觉输入是如何与更高水平的影响(如注意状态)相结合的。该项目旨在使用神经成像技术结合复杂的分析方法来解决这个问题，这些方法是最近开发的，用于测量刺激相关信息何时在不同大脑区域之间传输。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：特征绑定和颜色恒定。了解感觉输入与注意力在这些任务中相互作用的神经机制，将是理解大脑区域之间的相互作用如何产生我们的知觉体验的重大进步。

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.
