As a graduate student in the 1990s studying developmental neurobiology, she was drawn to the question of how the brain is built: how individual brain cells in a growing fetus somehow organize themselves into an organ capable one day of pondering the mysteries of life. Three different glia cell types have been found: astroglia or astrocytes. oligoglia or oligodendrocytes. microglia. In recent years it has become increasingly clear, that these glial cells also take over other functions in the brain. They may communicate in a sort of network which complements and or supports the neural network.
