Modulating visual and sensorimotor biases for attention

主动感知的核心要素之一是感知、记忆和反应选择之间的相互作用。以前的工作表明，要准确地研究这种影响的注意知觉需要考虑的反应背景。但是，在这些任务中，根据反应需求，哪些大脑区域参与了感知处理的加权，这方面的直接证据很少。我们最近的工作已经使用组合TMS-ERP来证明顶叶和额叶区域在整合知觉、记忆和反应相关信息中起着因果作用。这项建议的目的，是澄清这些表述的内容，它们如何随时间而变化，以及不同地区是否有不同的表述，用于不同的目的。

One core element at the heart of active perception is an interaction between perception, memory and response selection. Previous work has shown that to accurately study such effects of attention on perception requires considering the response context. But there is only scarce direct evidence as to which brain areas are involved with weighting perceptual processing according to response demands in these tasks. Our recent work has used combined TMS-ERP to demonstrate that parietal and frontal regions play a causal role in integrating perceptual, memory and response-related information. The objectives of this proposal are to characterise the content of these representations, how they can vary over time, and whether different representations exist in different areas for different purposes.
