 So neurofeedback, and I'm going to explain what it is. Neurofeedback, it has been around for like 60 years. It's the gold standard when it comes to correcting imbalances in the brain. And now with these imbalances that I'm referring to, a lot of people know this. You probably know this, that the brain has brainwaves. So the brain has brainwaves. There's, you know, alpha, there's beta, theta, different brainwaves, and they mean different things.
