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.

脑电信号的记录-脑电图或EEG -是一种广泛使用的，将神经功能与心理体验联系起来的一线方法。强大的EEG记录可以从无源电极进行非侵入性的，可以在很短的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以毫秒级的精度提供与刺激事件同步的神经活动的定时的实时记录。当与允许对脑电场进行充分空间采样的设备相结合时，脑电图记录和分析是对区域皮层功能与心理行为之间的联系进行基础研究的第一线方法，特别是在包括婴儿和儿童在内的敏感人群中。EEG记录也是测量神经认知功能的最灵活的方法之一。由于用于记录EEG的设备是便携式的，因此可以在各种设置和情况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。在皇后大学，有一些联邦资助的研究人员和研究项目目前使用EEG记录作为主要的研究方法，还有一些人试图将EEG记录与他们的主要评估相结合，以发现新的大脑行为关系。该提案的目标是为最先进的设备提供资金，这些设备将为这组研究人员创造，改善和扩展高质量EEG收集和分析的机会，这些研究人员的目标是发现社交，认知和情感功能的神经生理学基础。获得该设备将支持来自多个活跃实验室的HQP培训，培训内容涉及与多个有价值的环境中的生物电记录和解释直接相关的技能（即，医疗保健，研究），并在可转移的技能，如管理的大型数据集，信号处理和层析成像分析。
