 Now, I'm not going to get too deep into the science of neurofeedback. I'm going to kind of keep this surface level because you don't need to get a doctorate on this. You just need to understand, and hopefully it makes sense to you, how this would work. So neurofeedback, like I said, it's the gold standard. Now, when I say gold standard, I mean you look in the research. It is researched data.
