Until recently, it was thought that glial cells outnumbered neurones by 10 to one in the human brain. A new counting method, known as isotopic fractionation, now estimates the ratio as one to one (Physiolog Rev doi:10.1152/physrev.00042.2016). Astrocytes are highly variable in their morphology and express a large number of receptors, ion channels, and membrane transporters. But, beyond a rather vague notion that they provide homoeostasis and support for neurones, we still don’t understand much about what glial cells actually do.
