High density sensory arrays for cognitive neuroscience research.

我们目前的密集阵列脑电图（脑波）设备已成为支持阿尔伯塔大学认知神经科学日益增长的主要推动力。它已经成为一个不断扩大的跨部门和院系脑波研究人员社区的催化剂，研究人类认知和行动的大脑基础。我们计划利用拟议的设备进一步扩大和开展更多的前沿认知神经科学研究，以避免研究进展的延误。我们的设备要求的主要部分是9个脑电图传感器网，这是我们的研究参与者佩戴的电极“帽子”。这些网与我们的录音系统兼容，是最先进的。其中两个传感器网用于我们的脑成像（MRI）兼容脑电图系统，我们已经在阿尔伯塔大学医院安装了这个系统。我们所有的传感器网络都需要维护和修理，这意味着它们一次可能会停机几个星期。我们在此要求的额外传感器网络对我们的持续进展至关重要，以防止研究延误，并确保在任何给定时间可以运行多个研究参与者。请求资金的一部分将允许我们增强我们的多处理器数据分析服务器的计算能力，以支持我们的大型数据集以及我们的预处理和数据分析方法的复杂性。

Our current dense-array EEG (brainwave) equipment has been a major driving force in supporting an increasing presence of cognitive neuroscience at the University of Alberta. It has been a catalyst for an expanding community of brainwave researchers across departments and faculties, investigating the brain-basis of human cognition and action. We plan to further expand and conduct a higher volume of cutting-edge cognitive neuroscience research with the proposed equipment and to avoid delays in research progress. The main parts of our equipment request are nine EEG sensor-nets, which are the electrode "caps" that our research participants wear. These nets are compatible with our recording systems, and are state-of-the-art. Two of these sensor-nets are for our brain-imaging (MRI) compatible EEG system that we have installed at the University of Alberta Hospital. All of our sensor-nets require maintenance and repair, which can mean that they are out of commission for several weeks at a time. The additional sensor-nets we are requesting here are critical for our continued progress in order to prevent research delays, and ensure that more than one research participant can be run at any given time. A portion of the requested funds will allow us to enhance the computing power of our multi-processor data-analysis server to support the large size of our data sets and the complexity of our pre-processing and data-analysis methods.
