Heart Disease And Brain Blood Flow Regulation: Prelude To Dementia

The brain regulates changes in its own blood flow depending on how active its cells (neurons) are, by a mechanism called neurovascular coupling. When neurons become active, they send messages to nearby blood vessels causing them to dilate and bring in more blood. This increased... click to read more
