Neurons make up only 15 percent of our brain cells. Glial cells make up the rest.
Glial cells can control communication between neurons and play a central role in learning, but for years they were dismissed as mere putty.
Most neurological and some psychological disorders involve glia, so new therapies are targeting these cells. Via
Above: a look at my band new adult cells: if you can see it, it’s a new cell! Preexisting cells do not pick up the immunofluorescence antibody we use to identify new cells, but cute little red blood cells always do, so you have to just say ‘hi’ to those little guys and move on. If you can spot a dark nucleus inside the cell (like a dark yolk) it’s a new neuron, if it appears solid with no nucleus, it’s a new glia cell- give it a try, it’s tricky. It’s a 3 step process to make this determination: 1) ID the new cell 2) assign type and 3) confirm, each step done under a different fluorescence filter. The once underrated glias are not only important to researchers studying diseases, but to those like me who looked at learning and memory.
