Astrocytes are the primary metabolic regulators of the brain, producing metabolic fuels for neurons and regulating the blood-brain barrier.

“so astrocytes there they're basically like the metabolic regulators of the brain probably they do most of the the the production and turnover of metabolic fuels that say the neurons then depend on but they're they also help regulate the blood-brain barrier so they're intimately connected with with with the they have sort of pata sites which which wrap the capillaries in the brain and sort of help regulate the things that get into and out of the brain blow both water and you know metabolites”
