Standard Imaging Captures Only a Fraction of It The Endothelial Glycocalyx: A Microscopic Lining That Helps Regulate How Blood Moves Through the Smallest Vessels How Patented Microfluidic Chip ...

The brain is perhaps the most sensitive organ with respect to changes in blood flow and oxygen supply. Even brief interruptions in capillary flow (or "stalling") can indicate acute neurological issues ...

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 ...

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural ...

Researchers have discovered that a certain type of cell that sits on top of the brain's smallest blood vessels senses when their brain region needs energy. When glucose levels are low, these cells ...

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 ...

New University of Virginia School of Medicine research suggests an unexpected way doctors may be able to improve blood flow to the brain to battle Alzheimer's and other neurodegenerative diseases.

The brain is packed with neurons that are constantly in need of power, but there isn't really anywhere to store energy there. So the brain has a network of blood vessels that constantly supply it with ...

When we smell hot dogs, it may trigger memories of backyard barbeques or attending baseball games during childhood. During this process, the areas of the brain that control smell and long-term memory ...
