MRI-R2: Acquisition of Dense Array EEG for Research and Training across the Disciplines

该奖项由2009年美国复苏和再投资法案(公法111-5)资助(公法111-5大脑中的神经活动如何转化为“思维”是心理学和认知科学面临的关键问题。在国家科学基金会的支持下，迈阿密大学心理生理学中心将购买两个高密度脑电(EEG)系统来帮助回答这个问题。该中心位于牛津校区最近建造的心理学大楼内，将进一步推动迈阿密大学致力于高质量的教学和研究。该中心将使人们能够获得现代认知和行为神经科学技术，并将积累使用这些技术的专业知识。这些系统的获得将使来自广泛学科的研究人员能够用各种非侵入性手段来增强他们目前的行为方法，以测量和建模人类大脑功能。连续的头皮记录脑电及其衍生的事件相关电位(ERP)为了解心理处理背后的大脑活动提供了窗口。这项技术通过记录神经元在进行处理时产生的电磁场的快速变化来测量大脑活动。高密度(通道和256通道)脑电系统的获取将使中心的研究人员能够确定这种电生理活动的来源。通过利用数学建模技术的最新进展，这种空间信息可以用来将在脑电信号中观察到的活动定位到大脑的特定部分，从而阐明神经活动和心理功能之间的关系。计划的项目跨越多个学科，其中一些将涉及跨学科合作。这些包括将神经激活与工作记忆和类别学习联系起来，确定决策价值的神经相关因素，测量幼儿在游戏中的大脑活动，以及对比同一种族和其他种族人脸识别的神经成分。计划使用新设备的研究人员来自迈阿密大学所有五个校区的八个系，其中包括汉密尔顿的一个地区校区。除了支持教师和学生的研究工作外，这项收购还将使该中心能够提供独特的心理生理学和认知神经科学本科课程，体现“学生即学者”的学习模式。学生将获得收集和分析脑电数据的实践经验，扩大知识范围，将其特定学科以外的应用包括在内，并在最后一年设计和开展独立研究项目。这一分级课程倡议在关注本科培训方面是独一无二的，因为它与科学、技术、工程和数学(STEM)学科有关，并且是迈阿密培养参与型学习者的目标的典范。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5How neural activity in the brain translates into the "mind" is a critical question facing psychology and cognitive science. With support from the National Science Foundation, the Center for Psychophysiology at Miami University will acquire two high density electroencephalography (EEG) systems to help answer this question.Housed in the recently constructed Psychology Building on the Oxford campus, the Center for Psychophysiology will serve to further Miami University's dedication to high-quality teaching and research. The Center will enable access to modern cognitive and behavioral neuroscience technologies and will build expertise in their use. The acquisition of these systems will allow researchers from a broad range of disciplines to augment their current behavioral methodologies with a variety of noninvasive means of measuring and modeling human brain function.The continuous, scalp-recorded EEG and its derivative, event-related potentials (ERP), provide windows into the brain activities that underlie psychological processing. This technology measures brain activity by recording rapid changes in the electromagnetic fields generated by neurons as they engage in processing. The acquisition of high-density (64 channel and 256 channel) EEG systems will enable researchers at the Center to identify the sources of this electrophysiological activity. By taking advantage of recent advances in mathematical modeling techniques, this spatial information can be used to localize activity observed in the EEG signal to specific parts of the brain, and thus clarify the relationship between neural activity and psychological function. Planned projects span multiple disciplines, some of which will involve cross-disciplinary collaborations. These include relating neural activation to working memory and category learning, identifying the neural correlates of value in decision-making, measuring brain activities during play in young children, and contrasting the neural components of same-race and other-race face recognition. Researchers planning to use the new equipment come from eight departments spanning all five divisions of the Miami University campuses including a regional campus in Hamilton. In addition to supporting faculty and student research efforts, this acquisition will also enable the Center to offer a unique undergraduate curriculum in psychophysiology and cognitive neuroscience that embodies the "Student as Scholar" learning model. Students will obtain hands-on experiences in the collection and analysis of EEG data, broaden that knowledge to include applications outside of their own specific disciplines, and design and conduct independent research projects in their final year of study. This tiered curriculum initiative is one-of-a kind in its focus on undergraduate training as it relates to science, technology, engineering and mathematics (STEM) disciplines, and is exemplary of Miami's goal of creating the engaged learner.
