Quanta Theory - The Scars of the Multi-Thread Structure

The idea of sequentializing, you know, in our models of physics, that's done with reference frames. Now, interestingly, quanta mechanics is tha story of the the scars that you get from the fact that it isn't, in fact, sequentialized. So, in other words, that there is actually a multiway structure. And so the question would be, when we think about brains, and even the psychology of brains,  is it the case that we can see kind of the de canof the the scars, the shadows of the fact that what's happening isn't truly sequential?
