EEG suite for cognitive neuroscience of attention

注意力调节对传入的感觉信息的处理，并调节对适当目标和反应的选择。在我的实验室里，我们研究注意力如何影响复杂的日常行为。例如，我们感兴趣的是发现为什么人类会自动看向其他人看的方向，或者人类如何注意符号视觉信息（例如，手指点）。最近的一些行为研究表明，注意力可能会被这些非常有意义的刺激所吸引。这些数据有力地预测了人类大脑也可能专门对行为相关刺激做出反应。获得多设备EEG套件，包括高密度EEG系统（在单独的RTI提案中要求），远程眼动仪和双电隔离（DEI）外壳，将为我们提供调查这些问题的机会。脑电图揭示了注意力如何影响感觉处理以及大脑活动的时间特性。分析源建模技术被用来找到激活的大脑结构的一般空间位置。当与EEG相结合时，眼动跟踪提供了一种控制参与者表现的方法。当独立使用时，它提供了一个强大的注意力行为测量。将这两台设备安装在DEI内将大大提高我们的研究效率，因为外壳将确保EEG采集的可靠性和准确性以及明确的数据解释。该设备是成功完成拟议的研究计划所必需的。由于其独特的配置专为人类注意力的行为和神经特性的调查，它将使人们能够更好地理解注意力在复杂行为中的作用，并促进创造特殊的HQP培训机会。认知科学领域逐渐依赖于跨学科方法的应用，包括行为和神经成像方法。这些方法的结合有很大的潜力来解决大脑活动如何使人类行为的问题。

Attention modulates processing of incoming sensory information and regulates selection of appropriate goals and responses. In my lab, we study how attention influences complex everyday behaviors. For example, we are interested in discovering why humans automatically look in the direction of where others are looking or how humans pay attention to symbolic visual information (e.g., finger point). A number of recent behavioral studies suggest that attention may be uniquely engaged by these highly meaningful stimuli. This body of data makes a strong prediction that human brain may also be specialized to respond to behaviorally relevant stimuli. The acquisition of a multi-equipment EEG suite, comprised of a high density EEG system (requested in the separate RTI proposal), remote eye tracker, and a double electrically isolated (DEI) enclosure, would provide us with an opportunity to investigate these questions. EEG reveals how attention influences sensory processing as well as the temporal properties of brain activity. Analytical source modeling techniques are used to find general spatial locations of the activated brain structures. When combined with EEG, eye tracking provides a way to control participant's performance. When used independently, it provides a powerful behavioral measure of attention. Housing these two pieces of equipment within a DEI will greatly enhance our research productivity, as the enclosure will assure the reliability and accuracy of EEG acquisition as well as unambiguous data interpretation. This equipment is necessary for the successful completion of the proposed program of research. Due to its unique configuration tailored for the investigations of behavioral and neural properties of human attention, it will enable better understanding of the role of attention in complex behaviors and the facilitate creation of exceptional HQP training opportunities. The field of cognitive science is progressively relying on the application of interdisciplinary methodologies, including behavioral and neuroimaging methods. The combination of these methods has a great potential to address the question of how brain activity enables human behavior.
