Welcome to the Villeneuve Lab
The Villeneuve Lab is interested in how the brain ages, with a specific focus on factors that modify the association between brain lesions and cognitive performance. Our research is motivated by the fact that more than 25% of older adults are considered cognitively normal despite the presence of beta-amyloid in their brain, a hallmark of Alzheimer’s disease. This fact suggests that other factors interact with beta-amyloid to trigger cognitive deficits in Alzheimer’s disease. It also suggests that actions can be taken to prevent or postpone disease-related symptoms. The main focus of the Villeneuve Lab’s research is therefore to examine the factors that protect against, or worsen, the development of cognitive deficits in age-related neurodegenerative diseases.
We use a multi-tier approach that includes molecular PET imaging, MRI imaging, neuropsychological testing and genetics, combined with analytic tools such as deep learning, lasso regression and partial least squares regression.

New Article from the Villeneuve Lab September 2021 Julie Gonneaud’s latest paper was published in Nature Communications. Here, we developed a model that predicts brain age across the lifespan from resting state fMRI data using machine learning techniques. In the context of preclinical Alzheimer’s disease (AD), our model revealed that the presymptomatic phase of autosomal dominant AD is characterized by accelerated functional brain aging. [Papers]
