This study uses chemogenetic activation of pericytes in mice to show their ability to contract capillaries and cause hypoperfusion, particularly in limbic regions.

This study uses dual-calibrated fMRI to show reduced oxygen supply and consumption in MS patients without changes in oxygen extraction, suggesting impaired oxygen utilization or transfer.

This study uses calibrated fMRI to examine metabolic and blood flow changes during visuomotor adaptation in healthy humans, finding that CMRO2 decreases faster than BOLD or CBF but the flow-metabolism coupling ratio remains stable.

This study examines the relationship between aerobic fitness and cerebrovascular function in young adults, finding lower cerebral blood flow and higher cerebrovascular reactivity with higher fitness levels.

The paper examines the relationship between fitness, cerebral blood flow, and cerebrovascular reactivity in older adults, finding that higher fitness is associated with reduced cerebrovascular reactivity and altered hemodynamic responses.
