Attentional signals during visuomotor tasks

在这个项目中，我们的目标是了解在各种任务中使用了多少注意力，如抗扫视准备，视觉-听觉处理和视觉-运动表现。我们最近在一系列研究中检查了顶叶额叶网络（DeSouza et al. 2003; Everling & DeSouza, 2005； Chan and DeSouza摘要2009;2010;Ovaysikia et al. 2011）和视觉-听觉处理（Pynn & DeSouza SFN摘要2010），发现准备信号高于控制条件。问题仍然是，额叶皮层的这些预备信号涉及到多少注意力？另一个问题是什么类型的训练（短期的还是长期的）可以提高表现。我们利用专家将环境中的刺激转化为专门的视觉运动表演（吉他手和芭蕾舞演员）来研究这些问题。

In this proposed projects our aim is to understand how much attention is used in various tasks such as the antisaccade preparation, visual-auditory processing and visuo-motor performance. We have recently examined the parietofrontal network in a series of studies (DeSouza et al. 2003; Everling & DeSouza, 2005; Chan and DeSouza abstract 2009; 2010; Ovaysikia et al. 2011) and visual-auditory processing (Pynn & DeSouza SFN abstract 2010) and find preparatory signals are higher than control conditions. The question remains of how much attention is involved in these preparatory signals in frontal cortex? An additional question is what type of training (short or long-term) can make performance improve. We look at these questions using experts at converting stimuli from the environment into specialized visuomotor performance (guitarists and ballet dancers).
