Electroencephalographic (EEG) system for ERP research

有了申请者申请的资金，他的受训人员和同事将可以进入一个尖端的认知神经科学实验室，探索心理表征和作用于他们的心理过程是如何在大脑中执行的。有几种方法可以在这项重要任务中卓有成效地使用。当代认知神经科学的教训是，没有一种单一的方法是足够的，可以公平地说，功能神经成像方法已经成为这一努力的基本工具。其中，脑电(EEG)的高密度记录为认知神经科学家提供了最具成本效益的神经成像工具，具有足够高的时间精度(毫秒)，以阐明大脑是如何实现思维的。高密度采样，加上来源定位算法，将允许估计大脑活动的可能来源。正如我在最近资助的探索基金中所描述的那样，我们将使用这种脑电设备来调查注意力网络，我们将其解读为在时间、空间和任务领域实施自愿和反射性的心理处理资源分配。而且，当它可用时，我们将与我在达尔豪西4个学院(医学、科学、计算机科学和运动学)的当地合作者共享这台设备。

With the funds requested the applicant, his trainees, and colleagues will have access to a cutting-edge cognitive neuroscience laboratory for exploring how mental representations and mental processes which operate on them are implemented in the brain. There are several methods that can be used fruitfully in this important task. A lesson from contemporary cognitive neuroscience is that no single method will suffice, it is fair to say that methods for functional neuroimaging have become fundamental tools in this endeavor. Of these, high density recording of electrical brain potentials (EEG) offers the cognitive neuroscientist the most cost-effective neuroimaging tool with sufficiently high (millisecond) temporal precision to shed light on how the brain implements mind. The high density sampling, together with source-localization algorithms, will permit estimation of the likely sources of the brain activity. As described in my most recently funded Discovery Grant, we will use this EEG equipment to investigate the networks of attention, that we construe as implementing voluntary and reflexive allocation of mental processing resources with the domains of time, space and task. And, when it is available, we will share this equipment with my local collaborators in 4 Dalhousie faculties (Medicine, Science, Computer Science & Kinesiology).
