A High-Density Brain Electrophysiological Recording Facility for Queen's University

记录大脑电信号-脑电或EEG-是一种广泛使用的将神经功能与心理体验联系起来的第一线方法。健壮的脑电记录可以非侵入性地从被动电极进行，这些电极可以在短时间内以非常低的每次使用成本定位在头皮上。在大多数应用中，EEG提供与刺激事件同步的神经活动时间的实时记录，精度为毫秒。当与能够对大脑电场进行充分空间采样的设备相结合时，脑电记录和分析是基础研究区域皮质功能和心理行为之间联系的第一线方法，特别是在包括婴儿和儿童在内的敏感人群中。脑电记录也是测量神经认知功能最灵活的方法之一。由于用于记录脑电的设备是可移动的，因此可以在各种环境和环境下进行高质量的记录，并与其他行为和外周生理测量相结合。在女王大学，有一些联邦资助的研究人员和研究项目目前将脑电记录作为主要的研究方法，还有一些人试图将脑电记录与他们的初步评估相结合，以发现新的大脑与行为的关系。这项提议的目标是为最先进的设备提供资金，这些设备将为这群研究人员创造、改进和扩大高质量脑电收集和分析的机会，他们的目标是发现一系列重要心理领域的社交、认知和情绪功能的神经生理学基础。这些设备的购置将支持对一些现役实验室的HQP进行培训，使其掌握与多种有价值的环境(如保健、研究)中的生物电记录和解释直接相关的技能，以及大数据集管理、信号处理和断层扫描分析等可转让技能。

Recording of brain electrical signals - the electroencephalogram or EEG - is a widely used, first-line method for connecting neurological functioning to psychological experience. Robust EEG recordings can be conducted non-invasively from passive electrodes that can be positioned on the scalp within a short period of time at a very low per-use cost. In most applications, EEG provides an real-time record of the timing of neural activity synchronized to stimulus events with millisecond accuracy. When combined with equipment that allows for adequate spatial sampling of the brain electrical fields EEG recording and analysis is a first line method for basic research on the connections between regional cortical functioning and psychological behaviour, particularly in sensitive populations including infants and children. EEG recording is also one of the most flexible methods for measuring neurocognitive functioning. Because the equipment used to record EEG is transportable, high-quality recordings can be made in a wide variety of settings and circumstances and integrated with other behavioural and peripheral physiological measures. At Queen's University there are a number of federally funded researchers and research programs that currently use EEG recordings as a principal research method, and still others who seek to integrate EEG recordings with their primary assessments to discover novel brain-behaviour relations. The goal of this proposal is to provide funds for state-of-the-art equipment that will create, improve, and extend opportunities for high-quality EEG collection and analysis for this group of researchers whose goals are to discover the neurophysiological bases of social, cognitive, and emotional functioning across a range of vital psychological domains. Acquisition of this equipment will support the training of HQP from a number of active laboratories in skill sets directly relevant to bio-electrical recording and interpretation across a number of valued settings (i.e., health care, research), and in transferable skills such as management of large data sets, signal processing, and tomographic analysis.
