 So what does that mean? These are people that would otherwise have been more than likely put on a medication and been told, you stay on that medication for the rest of your life. And so what happens? They do the map first. Then they do their neurofeedback. And then they remap to make sure everything's where it's supposed to be. And lo and behold, anxiety scores improved. They got better. And they were not on the medication. So therefore, and I always say this, so then what does that mean was the cause of the problem?
