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 ...

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 CONVERSATION) – Neuroscientists have long assumed that neurons are greedy, hungry units that demand more energy when they become more active, and the circulatory system complies by providing as ...

"Amyloid and tau proteins are often considered the primary players in Alzheimer's disease, but blood flow and oxygen delivery are also critical,” said Amaryllis A. Tsiknia from USC's Mark and Mary ...

With each heartbeat, blood courses through your body. Some traverse arteries from the lungs back to the heart, and some navigate through capillaries in the thinnest layers of your eyelid, almost ...

Subtle changes in how blood flows through the brain and how brain tissue uses oxygen may be closely linked to Alzheimer's ...
