Electroencephalography (EEG) System

摘要脑电(EEG)是一种多用途的工具，可以精确地在时间上评估人类的皮质活动。时间和频率域的信息可以捕捉到大脑皮层的变化，这些变化反映了注意力等认知过程，以及对非侵入性脑刺激等实验干预的反应，使其成为斯坦斯博士研究计划的基石。目前，Staines博士的NeuroScan SynAmps2 EEG系统(Compumedics，于2005年购买)的使用寿命已到尽头。该系统已停产，原始公司不再支持维修。运行它的软件还没有升级，也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，系统功能所必需的脑电帽会随着时间的推移而磨损和相关的弹性丧失，影响电极的放置和与头皮的接触。更换盖子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。EEG系统的及时更换将使利用EEG评估注意力在调节感觉信息以增强运动控制方面的重要作用的研究得以继续，从而为感觉运动整合、认知神经科学和运动控制领域提供关键信息。EEG系统将对该团队研究与感觉运动神经可塑性、认知神经科学、眼球运动过程相关的神经机制至关重要；它将加强现有的合作，并促进新合作团队的发展。来自所有团队成员研究小组的HQP将获得培训和设备的使用。设备所需的脑电设备将取代史丹斯博士目前的系统。EEG系统的总成本为102,641.49美元，包括必要的放大器、CAPS和用于刺激传递、数据收集和分析的软件。

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.
