Episode 58

“The cells that I study make the insulating material myelin, that covers all of the wires in the brain,” says Dr Gonsalvez.

Our ‘wiring’ is formed by axons, the long stalks that grow out of the brain’s neurons and carry electrical signals to other neurons. Myelin is wrapped around axons to insulate the signals, just like wires in a house.

By studying the impact of the environment on myelin and how it forms, Dr Gonsalvez and his team hope to also understand what happens when it degrades and the electrical signal is disrupted, as happens in Multiple Sclerosis (MS).

“I’m starting to get really interested in whether or not those features of growth are impacted by your environment and conditions,” Dr Gonsalvez says.

“Any situation that you’re put in, any interaction you’re having with the environment, and any interaction you have with other people and anybody, will have an impact on your brain.”
