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.

"I like nonsense, it wakes up the brain cells." — Dr. Seuss.

Microglia are long-lived resident macrophages of the brain with diverse roles that span development, adulthood, and aging. Once thought to be a relatively homogeneous population, there is a growing recognition that microglia are highly specialized to suit their specific brain region.
