Cortical lamina-dependent blood volume changes in human brain at 7 T
Laurentius Huber,Jozien Goense,Aneurin J. Kennerley,Robert Trampel,Maria Guidi,Enrico Reimer,Dimo Ivanov,Nicole E. Neef,Claudine J. Gauthier,Robert Turner,Harald E. Möller +10 more
TL;DR: It is concluded that VASO offers good reproducibility, high sensitivity and lower sensitivity than GE-BOLD to changes in larger vessels, making it a valuable tool for layer-dependent fMRI studies in humans.
Journal ArticleDOI
Higher levels of cardiovascular fitness are associated with better executive function and prefrontal oxygenation in younger and older women.
Olivier Dupuy,Claudine J. Gauthier,Sarah Fraser,Laurence Desjardins-Crépeau,Michèle Desjardins,Said Mekary,Frédéric Lesage,Richard D. Hoge,Philippe Pouliot,Louis Bherer +9 more
TL;DR: Higher fit individuals who demonstrate better cardiorespiratory functions show faster reaction times and greater cerebral oxygenation in the right inferior frontal gyrus than women with lower fitness levels, suggesting that good cardiorespiratory functions can have a positive impact on cognition, regardless of age.
Journal ArticleDOI
Magnetic resonance imaging of resting OEF and CMRO₂ using a generalized calibration model for hypercapnia and hyperoxia.
TL;DR: A recently introduced generalization of calibrated MRI signal models that is valid for arbitrary combinations of blood flow and oxygenation change is applied to MRI and respiratory data during a predominantly hyperoxic gas manipulation, yielding a specific functional relationship between the resting BOLD signal M and the resting oxygen extraction fraction OEF₀.
Journal ArticleDOI
Age dependence of hemodynamic response characteristics in human functional magnetic resonance imaging
Claudine J. Gauthier,Cécile Madjar,Laurence Desjardins-Crépeau,Pierre Bellec,Louis Bherer,Richard D. Hoge +5 more
TL;DR: A calibrated fMRI method is used to explore vascular and metabolic changes that might bias BOLD comparisons and highlights the importance of ancillary measures such as ASL for the correct interpretation of BOLD responses when fMRI responses are compared across populations who might exhibit differences in vascular physiology.
Journal ArticleDOI
Advanced MRI techniques to improve our understanding of experience-induced neuroplasticity
Christine L. Tardif,Claudine J. Gauthier,Claudine J. Gauthier,Christopher J. Steele,Pierre-Louis Bazin,Andreas Schäfer,Alexander Schaefer,Robert Turner,Arno Villringer +8 more
TL;DR: An overview of advanced imaging techniques for an audience of cognitive neuroscientists that can assist them in the design and interpretation of future MRI studies of neuroplasticity encompasses MRI methods that probe the morphology, microstructure, function, and connectivity of the brain with improved specificity.
