Check out our latest publication in Frontiers Physiology, titled “Cerebrovascular Reactivity Mapping Without Gas Challenges: A Methodological Guide”. This work was lead by the excellent Joana Pinto, now a postdoc in Oxford, and covers breathing task methodology and resting state approaches for measuring CVR. This article is part of a special Frontiers “research topic” on Imaging CVR: Physiology, Physics, and Therapy.
