When the Air Hits Your Brain: Tales from Neurosurgery

by Frank T. Vertosick Jr.

We are all slaves to chaos—chaos in the scientific sense. Chaos theory predicts that the outcome of a chaotic process depends upon minuscule variations in the “initial conditions.” Example: a billiard ball rolling off the hood of a car. When placed in one spot, it rolls one way; placed one millimeter to the right or left of that spot, it rolls in a different direction altogether. Where the ball ends up depends entirely upon where we place it initially. The impact of the initial conditions has been named the “butterfly effect,” since, in the chaotic theory of weather, the beating of a butterfly’s wings in Asia can cause a hurricane in the southern Atlantic months later. Our lives evolve from our own butterfly effects. The tiniest perturbations in our youths, our “initial conditions,” generate profound alterations in our later lives. In my case, I had wanted to be a computer scientist, but no openings in my freshman computer-science courses existed. If I had jumped one or two places ahead in the registration line, I would have made it into freshman comp sci and never become a physician. What delayed my arrival at the registration office? I don’t remember—stopping for a hamburger, maybe, or speaking to a friend—but whatever this long-forgotten event was, it changed my life. If I could have taken cardiac surgery, as I had wanted, I would probably be one of the “best in the chest” now, and not a brain surgeon.
