The brain is comprised of billions of brain cells, a vast network of synapses and neurons transmitting electronic impulses like many stars in an infinite universe. A crucial support system for these data-laden neurons is glia, the brain’s immune cells, made up of oligodendrocytes, astrocytes, ependymal cells, and microglia. Astrocytes are the most numerous cell type present in the brain and perform a variety of … Continue reading New role identified for astrocytes in brain processing.
