An efficient algorithm for estimating brain covariance networks.

Autor: Marcela I Cespedes, James McGree, Christopher C Drovandi, Kerrie Mengersen, James D Doecke, Jurgen Fripp, Alzheimer’s Disease Neuroimaging Initiative

Publikováno v: PLoS ONE, Vol 13, Iss 7, p e0198583 (2018)

Often derived from partial correlations or many pairwise analyses, covariance networks represent the inter-relationships among regions and can reveal important topological structures in brain measures from healthy and pathological subjects. However b

Relative rate of change in cognitive score network dynamics via Bayesian hierarchical models reveal spatial patterns of neurodegeneration

Publikováno v: Statistics in Medicine. 39:2695-2713

The degeneration of the human brain is a complex process, which often affects certain brain regions due to healthy aging or disease. This degeneration can be evaluated on regions of interest (ROI) in the brain through probabilistic networks and morph

Publikováno v: Sleep. 44(7)

Study Objectives Growing evidence demonstrates pronounced alterations in rest–activity functioning in older adults at-risk for dementia. White matter degeneration, poor cardiometabolic functioning, and depression have also been linked to a greater

How many streamlines are required for reliable probabilistic tractography? Solutions for microstructural measurements and neurosurgical planning

Autor: Marcela I. Cespedes, Lee B. Reid, Kerstin Pannek

Publikováno v: NeuroImage, Vol 211, Iss, Pp 116646-(2020)

Diffusion MRI tractography is commonly used to delineate white matter tracts. These delineations can be used for planning neurosurgery or for identifying regions of interest from which microstructural measurements can be taken. Probabilistic tractogr

A Bayesian Hierarchical Approach to Jointly Model Cortical Thickness and Covariance Networks

Autor: Jurgen Fripp, James McGree, James D. Doecke, Kerrie Mengersen, Marcela I. Cespedes, Lee B. Reid, Christopher C. Drovandi

Publikováno v: Case Studies in Applied Bayesian Data Science ISBN: 9783030425524

Estimation of structural biomarkers and covariance networks from MRI have provided valuable insight into the morphological processes and organisation of the human brain. State-of-the-art analyses such as linear mixed effects (LME) models and pairwise

DETECTION OF LONGITUDINAL BRAIN ATROPHY PATTERNS CONSISTENT WITH PROGRESSION TOWARDS ALZHEIMER’S DISEASE

Autor: Marcela I. Cespedes

Publikováno v: Bulletin of the Australian Mathematical Society. 99:174-176

This thesis develops and applies statistical methodologies to model brain atrophy in humans among multiple brain regions and how this may change over time. Throughout this work, Bayesian multilevel models are progressively developed for single and mu

This paper investigates the complex factors that lead to early career teachers (ECTs) deciding to leave the profession. It extends prior studies to show the associations that different elements of preservice education (PSE), early career support, and
