Animals regularly experience periods of food uncertainty due to seasonal changes and environmental variability. Further, the changing climate is leading to more variable weather patterns, which alter environmental conditions, and can result in resource distributions being less predictable in space and time. How animals respond to uncertain conditions, and in particular a changing distribution of food resources, remains largely...
3D Texture Analysis of the Corpus Callosum in T1-Weighted MR Images of Children with a Traumatic Brain InjuryNARA Subscribed
Investigating traumatic brain injuries (TBI) in the developing brain is a challenging task. The superposition of an injury to the normal development trajectory can lead to brain impairments which are not obvious at diagnosis. T1-weighted MRI, acquired routinely post-injury, has the potential to better inform diagnosis, but is limited by qualitative assessment by radiologists. Using T1-weighted volume images, we investigated th...
Quantifying placebo and trial participation effects on cognitive outcome measures in aging dogsNARA Subscribed
The placebo effect, or the positive effects observed after an inert treatment which result from patients’ expectations for the therapy, is well documented in human medicine. However, in veterinary medicine, where owner’s expectations serve as a proxy for their pets, it remains underexplored, particularly for elderly dogs with cognitive decline. To address this gap, we examined 21 dogs (mean age: 12.85 years, SD: 1.46) from a p...
Voxel-wise insights into early Alzheimer’s disease pathology progression: the association with APOE and memory declineNARA Subscribed
Longitudinal investigation of the Apolipoprotein E (APOE) genotype’s impact on Alzheimer’s disease (AD) biomarker progression, focusing on amyloid beta (Aβ) accumulation and gray matter (GM) atrophy, integrating cognitive decline and baseline levels. Longitudinal florbetapir-PET and T1-weighted MRI data from 100 cognitively normal (CN) and mild cognitive impaired (MCI) participants both with considerable global Aβ accumulation...
