We recently examined potential relationship between tau protein uptake in medial temporal lobe (MTL) and volumetric measures of MTL subregions in a small dataset of Alzheimer’s disease patients. Since tau protein accumulates in MTL in a characteristic spatiotempoal pattern as … Continue reading
Quantification of medial temporal lobe (MTL) cortices, including entorhinal cortex (ERC) and perirhinal cortex (PRC), from in vivo MRI is desirable for studying the human memory system as well as in early diagnosis and monitoring of Alzheimer’s disease. However, ERC … Continue reading
The human perirhinal cortex (PRC) plays critical roles in episodic and semantic memory and visual perception. The PRC consists of Brodmann areas 35 and 36 (BA35, BA36). In Alzheimer’s disease (AD), BA35 is the first cortical site affected by neurofibrillary … Continue reading
Recently published paper by Wolk et al. in Neurobiology of Aging examines the involvement of hippocampal subfields and medial temporal lobe (MTL) cortical subregions in different stages of Alzheimer’s disease (AD). The study used high-resolution T2-weighted MRI scans of the … Continue reading
In our recent publication in Cerebral Cortex we compared in vivo and ex vivo MRI scans of the human hippocampus and evaluated to ability to match information between the two modalities. We were able to validate several of the features … Continue reading
Daniel Adler’s MICCAI 2016 paper “Probabilistic atlas of the human hippocampus combining ex vivo MRI and histology” describes substantial progress on building a comprehensive atlas of the human hippocampus that combines ultra-high resolution ex vivo MRI and serial histological imaging. … Continue reading
Linking structural neuroimaging data from multiple modalities to cognitive performance is an important challenge for cognitive neuroscience. In this study we examined the relationship between verbal fluency performance and neuroanatomy in 54 patients with frontotemporal degeneration (FTD) and 15 age-matched … Continue reading
We are constructing a computational, probabilistic atlas of the human hippocampal formation (HF) from postmortem, high-resolution 9.4T MRI and densely acquired histology. The human HF consists of several structures of the medial temporal lobe that play important roles in the … Continue reading
We have recently updated ANTs to perform processing of perfusion ASL images. The pipeline is designed to be consistent with the antsCorticalThickness pipeline for computing cortical thickness and incorporates state-of-the-art methods for correcting for motion and other confounds. Learn more … Continue reading
The complex and high-dimensional nature of medical images makes them difficult to incorporate into traditional linear model-based statistical analysis. One way of simplifying analysis of medical images is to use a dimensionality reduction technique. We designed a dimensionality reduction technique … Continue reading
