Star-Shaped Glial Cells Act as the Brain’s ‘Motherboard’.

The transistors and wires that power our electronic devices need to be mounted on a base material known as a “motherboard.” Our human brain is not so different — neurons, the cells that transmit electrical and chemical signals, are connected to one another through synapses, similar to transistors and wires, and they need a base material too.

But the cells serving that function in the brain may have other functions as well. PhD student Maurizio De Pittà of Tel Aviv University’s Schools of Physics and Astronomy and Electrical Engineering says that astrocytes, the star-shaped glial cells that are predominant in the brain, not only control the flow …[Read more]
