Astrocytes are critically involved in delivering glucose to neurons and shaping neuronal function and brain plasticity.

“And that's the so-called astrocyte. Astrocytes are one of several types of glia, the word glia means glue. But many people have taken that name, glia, glue, to think that, oh, the only thing that the astrocytes are doing is just kind of holding things together. Actually, the astrocytes are involved in delivering glucose to the neurons, they are critically involved in shaping your neuronal function and brain plasticity, the brain's ability to change in response to experience.”
