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.

在国家科学基金会的支持下，南卡罗来纳州大学的John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EEG/ERP记录实验室。高密度脑电/事件相关电位记录技术是近年来发展起来的一种新技术，它采用128个电极记录头皮电位。这些变化被假设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。该仪器允许测试皮层源发生器，并将用于认知心理学和认知神经科学的研究和研究培训。该系统有三个组成部分：1。NetAmps记录系统和辅助设备由电气测地线公司制造。用于EEG和ERP的高密度采集; 2.用于皮层电位源建模的软件; 3个相关设备，包括用于实验测试的计算机，网络交换机，以提供虚拟实验室，允许访问EEG/ERP设备。还向人员提供支助，以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行为和认知的神经基础研究的研究和研究培训，并从事假设驱动的基础科研。主题包括阅读、注意力和感知、大脑的发展以及大脑对注意力和物体认知的控制。例如，研究2至6个月大婴儿的注意力的心理生理学，并深入了解阅读中涉及的皮层处理，将是可能的。南卡罗来纳州的心理学系的大学目前运行的NSF夏季研究所的本科生和学生将被允许参加利用这种仪器的实验。它也将用于教学和研究目的，研究生和本科生。
