Both statements reflect genuinely different types of services. Some providers use general wellness brain training systems — classified by the FDA as General Wellness Devices — that provide the same feedback to every brain without targeting specific patterns. These can offer general relaxation and nervous system support, but they are not designed or cleared to address specific clinical conditions. At Grey Matters, we use clinical-grade, protocol-based neurofeedback guided by your individual brain map. If you’re seeking something that addresses a specific condition, history, or presenting challenge in your particular brain — rather than general wellness support — a brain map is essential to doing that responsibly.
