They're doing this in really different ways, but they both hope it's going to bring us closer to answering the question. That'll be next time on the show.

And after marathons, they saw that myelin decreased in the runners' brains, especially in the areas of the brain that are important for things like motor coordination, like how we move our bodies, and sensory processing. So after a marathon, there's less myelin. Is that a bad thing?

But there are some neurological diseases where myelin decreases and doesn't return to normal. Carlos thinks studying runners could help us better understand these disorders, like multiple sclerosis.

Another neuroscientist in the field, Yannick Poitelot, Told us the kind of scans the researchers took makes it hard to say, like, for sure that running caused the change in myelin. But he says that this study was really exciting. It's one of the first to show that human myelin could be used as an energy source. And he thinks it could inspire lots of new work in the field.
