The neural basis of selective attention is one of the most dominant issues in cognitive neuroscience. Although a network of brain areas have been implicated in filtering out unimportant information from the environment to focus on what is most important, it is not clear how the nodes in this network differ from one another i.e. which brain regions are critical for implementing which precise psychological functions. Transcranial magnetic stimulation (TMS) is a method of neural stimulation with which we can interfere with brain function while participants perform attentional tasks, to test the causal contribution of the stimulated region. The experiments in this proposal use TMS to stimulate the neural areas within the cortical network thought to support covert visuospatial attention. In addition to recording behaviour, these experiments combine TMS with brain-wave recording (TMS-EEG) to measure when and how different parts of the cortical network play their vital role. This research bears the potential to derive how these important psychological functions are represented in the brain, and has general validity in understanding how our brains control what we perceive.

选择性注意的神经基础是认知神经科学中最重要的问题之一。尽管大脑区域网络被认为可以过滤掉环境中不重要的信息，专注于最重要的信息，但目前还不清楚这个网络中的节点之间有什么不同，即哪些大脑区域对执行哪些精确的心理功能至关重要。经颅磁刺激(TMS)是一种神经刺激方法，我们可以在参与者执行注意任务时对大脑功能进行干预，以测试刺激区域的因果贡献。这个方案中的实验使用TMS来刺激皮质网络中的神经区，以支持隐蔽的视觉空间注意。除了记录行为外，这些实验还将TMS与脑波记录(TMS-EEG)相结合，以测量皮质网络的不同部分何时以及如何发挥其重要作用。这项研究有可能得出这些重要的心理功能在大脑中是如何表现的，并在理解我们的大脑如何控制我们的感知方面具有普遍的有效性。
