Iron Deposition and Distribution Across the Hippocampus Is Associated with Pattern Separation and Pattern Completion in Older Adults at Risk for Alzheimer's Disease

Author(s): Zhou J; Wearn A; Huck J; Hughes C; Baracchini G; Tremblay-Mercier J; Poirier J; Villeneuve S; Tardif CL; Chakravarty MM; Daugherty AM; Gauth ...

Elevated iron deposition in the brain has been observed in older adult humans and persons with Alzheimer's disease (AD), and has been associated with lower cognitive performance. We investigate ...

Modeling venous bias in resting state functional MRI metrics

Author(s): Huck J; Jäger AT; Schneider U; Grahl S; Fan AP; Tardif C; Villringer A; Bazin PL; Steele CJ; Gauthier CJ; ...

Resting-state (rs) functional magnetic resonance imaging (fMRI) is used to detect low-frequency fluctuations in the blood oxygen-level dependent (BOLD) signal across brain regions. Correlations bet ...

Motor sequences; separating the sequence from the motor. A longitudinal rsfMRI study

Author(s): Jäger AP; Huntenburg JM; Tremblay SA; Schneider U; Grahl S; Huck J; Tardif CL; Villringer A; Gauthier CJ; Bazin PL; Steele CJ; ...

In motor learning, sequence specificity, i.e. the learning of specific sequential associations, has predominantly been studied using task-based fMRI paradigms. However, offline changes in resting s ...

Comparing the effect of Cognitive vs. Exercise Training on brain MRI outcomes in healthy older adults: A systematic review

Author(s): Intzandt B; Vrinceanu T; Huck J; Vincent T; Montero-Odasso M; Gauthier CJ; Bherer L;

Aging is associated with cognitive decline. Importantly cognition and cerebral health is enhanced with interventions like cognitive (CT) and exercise training (ET). However, effects of CT and ET interventions on brain magnetic resonance imaging outcomes hav ...

White matter microstructural changes in short-term learning of a continuous visuomotor sequence

Author(s): Tremblay SA; Jäger AT; Huck J; Giacosa C; Beram S; Schneider U; Grahl S; Villringer A; Tardif CL; Bazin PL; Steele CJ; Gauthier CJ; ...

Efficient neural transmission is crucial for optimal brain function, yet the plastic potential of white matter (WM) has long been overlooked. Growing evidence now shows that modifications to axons ...
