Quotes About Glial

Most of our brain cells are glial cells, once thought to be mere support cells, but now understood as having a critical role in brain function. Glial cells in the human brain are markedly different from glial cells in other brains, suggesting that they may be important in the evolution of brain function.

The glial-derived neurotrophic factor (GDNF) that he referred to is a brain growth factor. It functions like a growth-promoting fertilizer in the brain. GDNF is made by glial cells, one of the major types of cells in the brain. Fifteen percent of our brain cells are neurons; the other 85 percent are glial cells.
