The objective of this Journal Club is to learn about this new method to measure cerebrovascular reactivity and its applications. Cerebrovascular reactivity is an important biomarker to vascular brain health. Resting state cerebrovascular reactivity quantifies the ability of blood vessels to vasodilate in response to a vasodilatory stimulus. The paper above describes in detail the method and a few applications.

Bio: Zacharie completed his undergraduate studies in Kinesiology and Clinical Exercise Physiology at Concordia University. Driven by a passion for research and brain health, he fast-tracked from a Master's degree to a PhD in Physics at Concordia University, under the supervision of Dr. Claudine Gauthier. Their lab focuses on implementing advanced quantitative MRI techniques to identify early biomarkers for various diseases and aging. His research emphasises the critical role of physical activity and exercise interventions in improving vascular brain health in aging.
