Newly mapped brain networks link far-flung regions

Astrocyte networks in mice link distant brain regions in ways nerve cell wiring does not

Blue and red brain cells called astrocytes appear inside of a mouse's brain. The image is on a black background.

Astrocytes, often relegated to "helper cell" status in the brain, form large and intricate networks that move cargo around. This view of a mouse's brain shows astrocytes forming one such network (near cells appear blue, far cells appear red).

Like ancient subway tracks buried deep underneath modern lines, a previously unknown transport system ferries materials around the brain.
