If you want to try a brain training website that works like biofeedback, I have created a free platform for clients that uses sound therapy with guidance from a questionnaire that I designed at (this link will open in a new window).

If you want to find another provider for neurofeedback in the Twin Cities, you can find a list by clicking the link below to a secure file in Google Drive (should be free of malware). From what I know, they are mostly working online due to COVID.
