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. This project will investigate the efficacy of task-activated fMRI as a biomarker for quantifying a therapeutic response in Parkinson's Disease (PD). The specific aims are to: (1) determine the sensitivity of task-activated fMRI for detecting changes in brain activation patterns occurring in PD patients on and off dopaminergic replacement therapy, (2) compare the relative sensitivity to therapeutic response of task-activated fMRI compared to established clinical outcome measures, and (3) determine the test-retest reliability of task-activated fMRI in healthy older adults.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。本计画将探讨以功能性磁振造影作为帕金森氏症治疗反应之量化生物标记物的效能。具体目标是：（1）确定任务激活的功能磁共振成像检测多巴胺能替代治疗前后帕金森病患者脑激活模式变化的灵敏度，（2）比较任务激活的功能磁共振成像与已建立的临床结局指标对治疗反应的相对灵敏度，（3）确定任务激活的功能磁共振成像在健康老年人中的重测信度。
