Acquisition of High-Density EEG/ERP Equipment for Cognitive Psychology and Cognitive Neuroscience

在美国国家科学基金会的支持下，南卡罗来纳大学的约翰·理查兹博士和他的合作者将购买必要的仪器，在心理学系建立一个高密度的脑电图/ERP记录实验室。高密度脑电/ERP记录技术是一项新近发展起来的技术，它使用128个电极记录头皮电位。据推测，这些变化与大脑皮层中的特定事件有关，而这些事件又与心理过程密切相关。该仪器允许对皮质源发生器进行测试，并将用于认知心理学和认知神经科学的研究和研究训练。该系统由三个部分组成：1。electrogeodesics公司生产的用于脑电图和ERP高密度采集的NetAmps记录系统及配套设备2. 皮层电位源建模软件；3 .相关设备包括一台用于实验测试的计算机，网络交换机提供一个允许访问EEG/ERP设备的虚拟实验室。还向人员提供支助，协助安装和维护设备和实验室。主要接触仪器的科学家参与研究和研究训练，研究行为和认知的神经基础，从事假设驱动的基础科学研究。主题包括阅读，注意和感知，大脑的发展和大脑控制的注意和对象认知。例如，研究2至6个月大的婴儿的注意力心理生理学，并深入了解与阅读有关的皮层处理过程，将成为可能。南卡罗来纳大学心理学系目前为本科生运营一个NSF暑期研究所，学生将被允许参与使用该仪器的实验。它也将提供给研究生和本科生用于教学和研究目的。

With National Science Foundation support Dr. John Richards and his collaborators at the University of South Carolina will purchase instrumentation necessary to establish a high-density EEG/ERP recording laboratory in the Department of Psychology. High-density EEG/ERP recording is a recently developed technique in which 128 electrodes are used to record scalp electrical potentials. These changes are hypothesized to be related to specific events in the cortex that in turn are closely related to psychological processes. The instrumentation allows the testing of cortical source generators and will be used for research and research training in cognitive psychology and cognitive neuroscience. The System has three components: 1. A NetAmps recording system and ancillary equipment made by Electrical Geodesics Inc. for high-density acquisition of EEG and ERP; 2. Software for source modeling of the cortical potentials; 3 related equipment including a computer for experimental testing, network switches to provide a virtual laboratory to allow access to the EEG/ERP equipment. Support is also provided to personnel to aid in the installation and maintenance of the equipment and laboratory.The scientists with primary access to the instrumentation are involved in research and research training in the study of the neural basis of behavior and cognition and engage in hypothesis driven basic scientific research. Topics include reading, attention and perception, the development of the brain and brain control of attention and object cognition. It will be possible for example to study the psychophysiology of attention in infants aged 2 to 6 months and gain insight into the cortical processing involved in reading. The University of South Carolina Department of Psychology currently runs an NSF Summer Research Institute for Undergraduates and students will be permitted to participate in experiments which utilize this instrumentation. It will also be available for teaching and research purposes to both graduates and undergraduates.
