Nov 30, 2022 · Neurons are associated with support cells called glia. 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. Microglia are the brain’s immune cells. A previously unknown role for microglia has now been uncovered: providing negative feedback to active neurons, to help the brain process information ...Jun 26, 2020 ...

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.
