Modulating visual and sensorimotor biases for attention

主动知觉的一个核心要素是知觉、记忆和反应选择之间的相互作用。先前的研究表明，要准确地研究注意力对感知的影响，需要考虑反应环境。但是，只有很少的直接证据表明，哪些大脑区域参与根据这些任务的反应需求来加权感知处理。我们最近的研究结合了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方面起着因果作用。本建议的目的是描述这些陈述的内容，它们如何随时间变化，以及不同领域是否存在不同目的的不同陈述。

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.
