. PMID 24484974. Glia (including astrocytes, microglia, and oligodendrocytes), which represent nearly all cells while in the brain, have most of the similar receptors as neurons, secrete neurotransmitters and neurotrophic and neuroinflammatory variables, Management clearance of neurotransmitters from synaptic clefts, and they are intimately linked to synaptic plasticity. Regardless of their prevalence and spectrum of features, appreciation in their prospective basic value has been elusive since their identification inside the mid-1800s, and only rather recently have they been attaining their because of respect.
