SPATIAL AND TEMPORAL PATTERNS OF FUNCTIONAL ACTIVATION

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 这个项目的主要目标是(I)模拟和可视化从[150]water PET和1.5T和4T fMRI神经认知研究中获得的功能激活的空间和时间模式，(Ii)系统地评估用于受试者之间的脑图像配准的自动算法的准确性，以及(Iii)量化配准算法的性能如何作为用于驱动配准的特征层次和用于计算配准优度的特征的函数。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The major goals of this project are (i) to model and visualize spatial and temporal patterns of functional activation obtained from [15O]water PET and 1.5T and 4T fMRI neurocognitive studies, (ii) to systematically evaluate the accuracy of automated algorithms for intersubject brain image registration, and (iii) to quantify how the performance of registration algorithms varies as a function of the hierarchy of features used to drive the registration and the features used to compute goodness of registration.
