This study aims to advance the understanding of gray and white matter neurodegeneration linked with vascular contributions to cognitive impairment and dementia (VCID) by developing novel post-mortem MRI protocols and computational tools for multi-modal, multi-scale analysis of brain MRI, histopathology, and proteomics.
MRI and histopathology can provide insights into disease mechanisms and uncover therapeutic implications in age-related cognitive impairment and dementia. In this project we are working to standardize MRI and histology protocols, introduce novel tools for postmortem analysis, and provide extensive imaging and biomaterial resources to drive progress in research on VCID in Alzheimer’s disease (AD) and AD-related dementia (ADRD).
In particular, we are pursuing four aims:
Figure 1. Ex vivo MRI of the hippocampus. (A): MRI co-registered to H&E and SM31-stained images. Major axonal pathways and their orientations can be qualitatively examined. (B): Using hippocampal atlas, pathways between subfields can be reconstructed. Part of the perforant pathway between entorhinal cortex (EC) and dentate gyrus can be reconstructed. (C): Reconstruction of the perforant pathway and Alveus/fimbria, showing the FA values along the perforant pathways, EC volumes, and streamline density.
