The talent "code" is built on revolutionary scientific discoveries involving a neural insulator called myelin, which some neurologists now consider to be the holy grail of acquiring skill. Here's why. Every human skill, whether it's playing baseball or playing Bach, is created by chains of nerve fibers carrying a tiny electrical impulse—basically, a signal traveling through a circuit. Myelin's vital role is to wrap those nerve fibers the same way that rubber insulation wraps a copper wire, making the signal stronger and faster by preventing the electrical impulses from leaking out. When we fire our circuits in the right way—when we practice swinging that bat or playing that note—our myelin responds by wrapping layers of insulation around that neural circuit, each new layer adding a bit more skill and speed. The thicker the myelin gets, the better it insulates, and the faster and more accurate our movements and thoughts become.
Myelin is important for several reasons. It's universal: everyone can grow it, most swiftly during childhood but also throughout life. It's indiscriminate: its growth enables all manner of skills, mental and physical. It's imperceptible: we can't see it or feel it, and we can sense its increase only by its magical-seeming effects. Most of all, however, myelin is important because it provides us with a vivid new model for understanding skill. Skill is a cellular insulation that wraps neural circuits and that grows in response to certain signals. The more time and energy you put into the right kind of practice—the longer you stay in the continuous learning zone, firing the right signals through your circuits—the more skill you get, or, to put it a slightly different way, the more myelin you earn. All skill acquisitions, and therefore all talent hotbeds, operate on the same principles of action, no matter how different they may appear to us. As Dr. George Bartzokis, a UCLA neurologist and myelin researcher, put it, "All skills, all language, all mu- sic, all movements, are made of living circuits, and all circuits grow according to certain rules."
