How do blood vessels stay strong, flexible, and responsive to the body's changing need for oxygen and nutrients? The answer lies not only in biology—but also in physics. Researchers at Åbo Akademi ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

Though it accounts for just two percent of the body’s weight, the brain consumes a whopping 20% of its total energy. To get the energy it needs for more complicated tasks, the brain has evolved a ...

When blood moves through your body, it exerts a frictional force on the walls of blood vessels. This force, known as fluid shear stress, has important effects on vascular development, function, and ...

New noninvasive tools reveal that subtle shifts in brain blood flow and oxygen use may mirror key markers of Alzheimer’s risk ...
