Vertebrate Physiology

Did you know that your brain is made up of more than just neurons? In reality, it’s a mix of many different types of cells. Glial (housekeeper) cells are the most common cell type in the CNS. These have endless functions, from providing nutrients, to repairing damaged tissue, to physically keeping neurons in place.

It would be an oversimplification to think that neurons get all the action. Sure, they’re the jocks of your brain. But don’t overlook the guys in the background. You know…the geeky glial cells. They can surprise you! Research on these supporting cells is turning up some interesting results. One particularly cool discovery: when it comes to lulling you to sleep after a long day, astrocytic glial cells steal the spotlight.
