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.

Neuroscientists have long believed that glia outnumber neurons by 10:1 (or more). However, recent investigations suggest that in some regions of the brains of humans and other primates, that ratio is closer to 1:1. However, the ratio of glia to neuron from region to region varies considerably. The researchers have created the most detailed cell atlas yet of the adult human brain. The atlas reveals information about each cell’s gene activity and epigenome—the changes to a cell’s DNA and chromosomes that alter genetic activity. The findings also show that, besides variation among brain regions, there is variation …Neural stem cells (NSCs) play vital roles in brain homeostasis and exhibit a broad repertoire of potentially therapeutic actions following neurovascular injury.
