1. Astrocytes: These cells provide structural support to neurons and help regulate the chemical environment in the brain. They also play a role in the formation of synapses and the maintenance of the blood-brain barrier.
2. Oligodendrocytes: These cells produce myelin, a fatty substance that insulates and protects nerve fibers in the brain. Myelin helps to speed up the transmission of electrical signals between neurons.
3. Microglia: These cells are the immune cells of the brain and play a crucial role in protecting the brain from infection and inflammation. They also help to remove debris and dead cells from the brain.
4. Radial glial cells: These cells serve as a scaffold for the migration of neurons during brain development. They also play a role in guiding the growth of axons and dendrites, the extensions of neurons that form connections with other neurons.
