I'm thinking about it differently. It's neurological. But a study found that different things happen in the brain of a stutterer. They used the scientific method and had a control group of non-stutterers. That study seems to be good. I wish I had the link for that. But the brain is so complex. I've had an MRI and there is a bigger space where the expressive language happens in the middle. I was getting it for a different reason, but the MRI person said that the extra space was something common with stutterers. I haven't heard before that there is a scar that causes stuttering. But I think that's interesting. Post the pics (you have a right to get a copy of your own file contents).
