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)研究对象的核磁共振成像和microPET成像，(2)从研究对象获得的数据收集和分析方法--神经内分泌(激素)测量，以及(3)研究对象心理生理测量的数据收集和分析方法。核心将负责维护项目所需的协议、硬件和分析方法。该核心还将在三个领域(神经成像、神经内分泌和心理生理学)向项目工作人员提供数据获取和分析方法方面的培训 措施)。将实施定期质量保证计划。此外，核心的成像部分将负责开发新的图像采集和图像分析方法，这些方法将提高成像灵敏度，减少图像伪影(功能磁共振扫描中的失真和局部信号丢失)，并改进MRI和microPET的动物成像方法。

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.
