Microtransponders, which developped the SAINT™ System, a wireless neurostimulation technology platform to treat neurological disease. He is excited about a possible application to stuttering. Nature has already published an article on treating tinnitus in an animal model.
The website, technology, and research looks solid, and should not be rejected off hand. I will write to them and ask whether they have ever considered stuttering. I am not exactly sure how a treatment for stuttering should work. As far as I am aware, stimulation has only increased and never decreased stuttering. However, every new approach should be checked for.
Let us assume the technology works, would you accept having implants, even if very small, implanted in your brain? I can only see severe stutterers considering this option.
