Development of Neuroimage Analysis Laboratory

该奖项允许华盛顿大学心理学系购买仪器来存储和分析功能性磁共振成像和正电子发射排版数据。目前，该系的认知科学家使用位于华盛顿大学医学院校园的功能磁共振成像和PET机器进行认知研究，他们必须分析那里的结果数据。这使得高级研究人员和学生都很难方便和连续地访问。所提供的仪器将允许将这些信息传输到心理学系，在那里可以进行分析。该系统包括：一台服务器计算机，它将接收大型数据结构并存储图像，以便分发到其他工作站;一个SGI工作站，它利用已经开发的程序提供人类皮层的二维表面重建;三个工作站;一个电子中枢;一个彩色打印设备;一个兼职技术员，他将负责系统的初始开发和维护。 目前正在进行的两个项目将立即使用该系统。两者都涉及行为认知成分的神经基础。第一个- PET激活研究的话-地址这些地区的大脑积极参与处理不同方面的话和神经基础的注意力控制系统，协调这些过程。第二个项目-学习和记忆的成像研究-研究涉及从情景、语义和程序记忆系统中编码和提取信息的不同方面的大脑区域。 该设备还将用于培训认知神经科学领域的研究生和博士后研究员。

This award permits the Psychology Department at Washington University to purchase instrumentation to store and analyze functional magnetic resonance imaging and positron emission typography data. Currently cognitive scientists in the department conduct cognitive research using fMRI and PET machines located at the Washington University Medical School campus and they must analyze the resultant data there. This makes convenient and continuous access difficult both for senior researchers and students. The instrumentation provided will allow transmission of this information to the Psychology Department where it can be analyzed. The system includes: a server computer which will receive the large data structures and store the images for distribution to other work stations; an SGI Work Station that takes advantage of programs that have been developed to provide 2-dimensional surface reconstructrions of the human cortex; three work-stations; an eithernet hub; a color printing device; a half-time technician who will be responsible for the initial development and maintenance of the system. Two projects currently under way will make immediate use of the system. Both address the neural underpinnings of cognitive components of behavior. The first - PET Activation Studies of Words - addresses those areas of the brain which are actively engaged in processing distinct aspects of words and the neural underpinnings of the attentional control systems that coordinate such processes. The second project - Imaging Studies of Learning and Memory - addresses those brain areas which are involved in the distinct aspects of encoding and retrieval of information from episodic, semantic and procedural memory systems. This equipment will also be used for training graduate students and postdoctoral fellows in the area of cognitive neuroscience.
