Biofeedback uses physiological signals (EMG, HRV, GSR, temperature). Neurofeedback uses brain activity (EEG). Both share the principle of real-time feedback; neurofeedback is a brain-focused subset.
View evidence by condition
Multimodal biofeedback (HRV + GSR + EEG) is often more effective than a single modality. The Studies & Certification page includes the evidence matrix and evaluation bubbles (Strong, Moderate, Preliminary) by condition, including conditions where neurofeedback or biofeedback have stronger evidence.
| Criteria | Neurofeedback | Biofeedback (broader) |
|---|---|---|
| Main signal focus | EEG / brain activity | HRV, GSR, EMG, temperature, optional EEG |
| Typical objective | Brain regulation patterns | Autonomic and psychophysiological regulation |
| Best framing | Specific protocol by indication | Multimodal protocol by indication |
Broadly, neurofeedback often focuses on EEG patterns and brain training; multichannel biofeedback may combine HRV, GSR, EMG and other channels in the same therapeutic ecosystem, depending on protocol and device.
The boundary is not rigid in clinical practice: indication, training and evidence matter. Also read Scientific basis of biofeedback and HRV training; evidence by condition in Studies & Certification.
If you are choosing between approaches, prefer a conversation with a trained clinician over label lists: the same device can host different channels depending on the training plan.
See Studies for the table and evaluation bubbles by condition.
