Oh, that’s cool
Myelin, you probably know, is the insulation on our brainal wires. It keeps them from arcing and sparking as they cross each other. That’s my very in depth medical understanding, anyhow.
Turns out, when you practice – whether a sport or an instrument – the actual measurable physical mechanism by which you get better is you grow more myelin sheath. Your insulation gets thicker!
I read that interesting fact this week and I cannot remember where. Grok backs me up.
It’s touched on briefly in this article (item 18) but I’m only linking to it because I stole the illustration from them. I dunno. I think they might be selling supplements.
