New research on tiny capillaries and cells called pericytes details how blood moves through over 400 miles of total vasculature in the human brain. While the human brain has over 400 miles of total ...

With age, the brain’s ability to clear aggregating proteins such as Aβ wanes. In the November 9 Nature, researchers led by Jonathan Kipnis at Washington University in St. Louis suggest a reason why.

Neurons intertwine with small blood vessels in the brain, but how do the two communicate? With elaborate three-dimensional reconstructions of electron microscopy images, scientists led by Jie-Min Jia, ...

For instance, in the vasculature of the brain, blood vessels oscillate, expanding and contracting as needed. When there is neural activity, the arterioles expand to increase blood flow, oxygen and ...
