Learning new skills or information from approximately age 25 onwards occurs through a process of focused effort followed by rest, with rewiring happening during deep sleep.

“From about, about, I want to emphasize approximately age 25 onward neuroplasticity occurs through the process that is exactly as I described before, focus, rest, focus, rest, we focus very intensely. We can't do the thing. We can't do the new movement. We can't do the golf swing. We can't learn the math. We try, we try, we try, we try, we sleep a few nights. And then all of a sudden we can do it, right, because the rewiring actually occurs during deep rest or naps, but mostly during deep sleep.”
