Scientific basis, autonomic nervous system, heart rhythm and history.
Explore the science behind biofeedback: stress responses, autonomic nervous system, vagus nerve, heart rate variability (HRV), neurofeedback and the history of the field, in plain language.
Three shortcuts for science, evidence and therapy. Not an online diagnosis.

For the evidence table by condition and levels (strong, moderate, preliminary), see Studies & Certification. Below are background science topics.
Themes that explain how biofeedback is used in practice.
This research section is educational, not medical advice for your individual situation. Each topic explains background science (such as autonomic nervous system, heart rate variability, or neurofeedback vs biofeedback) so you can read the evidence matrix and therapy condition pages with context. The aim is approachable language, with mechanisms and limits of evidence clearly stated. The same certified devices and training support research reading, evidence by condition, and therapy when you need care.
Looking for sessions or a referral? Use the therapist network or booking. Practitioners can tie research reading to certified training and Mandelay Q9 or SCIO devices with CE marking, consistent with the platform's commercial policy.
Research, therapy, studies and training share one platform.
