CORE-- BIOLOGICAL MEASURES

生物测量核心将为三个主要领域的科学项目提供支持：(1)研究对象的MRI和microPET成像；(2)研究对象神经内分泌（激素）测量的数据收集和分析方法；(3)研究对象心理生理测量的数据收集和分析方法。核心人员将负责维护项目所需的协议、硬件和分析方法。该中心还将向项目工作人员提供关于三个领域（神经成像、神经内分泌和心理生理学）的数据采集和分析方法的培训

The biological measures core will provide support for the scientific projects in three main areas - (1) MRI and microPET imaging of study subjects, (2) data collection and analysis methods neuroendocrine (hormonal) measures obtained from study subjects, and (3) data collection and analysis methods for psychophysiological measures on study subjects. The core will be responsible for maintaining protocols, hardware and analysis methods that are necessary for the projects. The core will also provide training to project staff in data acquisition and analysis methods in each of the three domains (neuroimaging, neuroendocrine and psychophysiological measures). Regular quality assurance programs will be implemented. In addition, the imaging portion of the core will be responsible for developing new image acquisition and image analysis methods that will improve the imaging sensitivity, decrease image artifacts (distortion and localized signal loss in functional MRI scans), and improve animal imaging methods for both MRI and microPET.
