Summary Electroencephalography (EEG) is a versatile tool that can assess human cortical activity with precise temporal accuracy. Information in time and frequency domains can capture cortical changes reflective of cognitive processes, such as attention, and in response to experimental interventions, such as non-invasive brain stimulation, making it a cornerstone of Dr. Staines' research program. Currently, Dr. Staines has a NeuroScan SynAmps2 EEG system (Compumedics, purchased in 2005) that has reached the end of its lifespan. The system is discontinued and repairs are no longer supported by the original company. The software to run it has not been upgraded and does not run on Windows 10, the operating system used by all lab computers. In addition, the EEG caps necessary for system function have wear and associated loss of elasticity that occurs over time, impacting the electrode placement and contact with the scalp. Replacing the caps will enhance the accuracy of the readings by improving the contact with the skin and will include multiple sizes to provide options to further improve the fit. A timely replacement of the EEG system will allow for the continuation of studies that use EEG to evaluate the important role of attention in modulating sensory information to enhance motor control, thus providing critical information to the fields of sensorimotor integration, cognitive neuroscience and motor control. The EEG system will be critical for the team's studies of the neural mechanisms associated with sensorimotor neuroplasticity, cognitive neuroscience, oculomotor processes; and will both strengthen existing collaborations and enhance development of new collaborative teams. HQP from all of the team members' research groups will have access to training and use of the equipment. Equipment The EEG equipment requested will replace Dr. Staines' current system. The total cost for the EEG system, including necessary amplifiers, caps, and software for stimulation delivery, data collection, and analysis, is $102,641.49.

摘要脑电图（EEG）是一种多功能的工具，可以精确的时间精度评估人类皮层活动。时域和频域的信息可以捕捉反映认知过程（如注意力）的皮层变化，以及对实验干预（如非侵入性脑刺激）的反应，这使其成为斯泰内斯博士研究计划的基石。目前，斯泰内斯博士拥有的NeuroScan SynAmps 2 EEG系统（2005年购买的计算机）已达到使用寿命。该系统已停止使用，原公司不再支持维修。运行它的软件尚未升级，并且不能在所有实验室计算机使用的操作系统Windows 10上运行。此外，系统功能所需的EEG帽会随着时间的推移而磨损和相关的弹性损失，从而影响电极放置和与头皮的接触。更换帽将通过改善与皮肤的接触来提高读数的准确性，并将包括多种尺寸，以提供进一步改善贴合性的选项。及时更换脑电图系统将允许继续研究，使用脑电图来评估的重要作用，注意力在调节感觉信息，以提高运动控制，从而提供关键信息的领域的感觉运动整合，认知神经科学和运动控制。EEG系统将对团队研究与感觉运动神经可塑性，认知神经科学，眼神经过程相关的神经机制至关重要;并将加强现有的合作并促进新合作团队的发展。来自所有团队成员的研究小组的HQP将获得培训和使用设备的机会。 设备所要求的脑电图设备将取代斯泰内斯博士目前的系统。EEG系统的总成本（包括必要的放大器、电容器和用于刺激输送、数据收集和分析的软件）为102，641.49美元。
