NIA R21 grant: Functional MRI and Alzheimer’s disease (score 154 (12.6%)). Cordes (PI) 12/1/2006-11/30/2008

The overall goal of this project is to obtain an accurate statistical map of memory activation in the hippocampus (and associated structures in the limbic system) in older subjects, age 60 to 75. The successful completion of our objectives would lead to an fMRI-based diagnostic test for memory impairment to help characterize abnormal memory function in people at risk for Alzheimer’s disease.
