Neurofeedback is a form of biofeedback. The difference is the signal used for feedback: EEG neurofeedback uses measurements of electrical brain activity, while other forms of biofeedback may use muscle activity, skin temperature, or the timing of heartbeats.
Seeing the terms side by side on a provider’s website can make them sound like separate options. “Biofeedback” names the broader category; “neurofeedback” identifies a particular kind within it. Knowing which signal a provider uses helps clarify what you would actually do in a session.
What biofeedback means
Biofeedback uses instruments to measure a body process and return information about it to the person receiving feedback. The professional definition of biofeedback, developed by AAPB, BCIA, and ISNR, includes measurements of brain activity, heart function, breathing, muscle activity, and skin temperature.
For example, someone might watch a muscle-activity display while practicing relaxing a muscle. The feedback makes a change visible that might otherwise be difficult to notice. The signal, the exercise, and the goal all matter when describing the method.
“Biofeedback” alone does not tell you which sensors a provider uses or what you will be asked to practice. Ask for the full name of the approach.
What neurofeedback adds
In EEG neurofeedback, scalp sensors record electrical activity associated with the brain. EEG stands for electroencephalography. MedlinePlus explains how EEG recording works: electrodes collect signals that a recording system turns into visible patterns.
Neurofeedback uses information from that recording to provide feedback during training. BCIA’s guide to biofeedback and neurofeedback designations also calls neurofeedback “EEG biofeedback.”
A diagnostic EEG and an EEG neurofeedback session have different purposes. Using scalp sensors during training does not, by itself, make the session a diagnostic examination. The AAPB standards for biofeedback explain that biofeedback alone cannot make a diagnosis. Ask what the recording is being used for and what conclusions the provider can draw from it.
Compare the signal and the session activity
The table describes examples of feedback methods, not a list of services offered by Vibrant Life Therapy. Mayo Clinic’s overview of biofeedback types describes muscle, temperature, heart, and brain measurements. For HRV specifically, a research guide to HRV biofeedback explains heartbeat timing and the use of paced breathing with feedback.
| Method | Signal measured | Typical feedback or activity | Question for the provider | What the signal does not establish |
|---|---|---|---|---|
| Heart rate variability (HRV) biofeedback | Variation in the time between successive heartbeats; breathing may also be monitored | A heart-rate display, often paired with guided, paced breathing | How will you measure heartbeat timing and guide the breathing practice? | A heart recording is not an EEG recording of brain activity. |
| Surface EMG biofeedback | Electrical activity from a selected muscle, recorded through skin sensors | Watch muscle-activity feedback while practicing changing muscle tension | Which muscle are you monitoring, and what will I practice? | A change at one muscle does not describe all muscle activity in the body. |
| Thermal biofeedback | Skin temperature, often at a finger or toe | Watch temperature feedback while practicing relaxation | Where is temperature measured, and how will you interpret changes? | A skin-temperature reading is not a measurement of brain activity. |
| EEG neurofeedback | Electrical brain activity recorded at the scalp | Visual or sound feedback linked to selected features of the recording; the task depends on the protocol | Which EEG feature drives the feedback, and what am I expected to do? | The feedback display alone does not establish a diagnosis or a benefit in daily life. |
The distinction between HRV and heart rate is easy to miss. Heart rate describes how often the heart beats; HRV describes variation in the intervals between beats. An HRV session may display heart rate and breathing together, but it does not use the same signal as EEG neurofeedback.
Likewise, a finger-temperature sensor and a scalp electrode answer different measurement questions. Neither becomes a more suitable option simply because its display looks more technical.
Where InfraLow neurofeedback fits
InfraLow, also called infra-low frequency or ILF neurofeedback, sits within EEG neurofeedback. It is an approach that includes very slow components of the recorded signal. It should not be treated as interchangeable with every EEG training protocol.
A published ILF neurofeedback trial describes feedback through a movie, sound, and tactile cues, without requiring active attempts to control the signal. That description helps explain the session format; it does not establish benefits for every person or condition. The study involved adults receiving rehabilitation after brain injury, a specific population.
Vibrant Life Therapy’s InfraLow neurofeedback service page describes scalp and ear sensors and watching a visual program during sessions. For more detail about the appointment format, read the clinic’s guide to what happens during InfraLow neurofeedback.
The clinic describes these sensors as measuring activity, with no electrical stimulation used in its InfraLow sessions. Recording a signal and delivering stimulation are different equipment functions, a distinction also described in the AAPB standards. If another provider uses a different system or combines methods, ask them to explain exactly what each device does.
Questions that make a comparison useful
Once the terminology is clear, the next conversation can be specific. You can bring these questions to a qualified provider:
- Which signal and protocol do you use, and why are you proposing them for this concern?
- What would I, or the person I care for, do during a session?
- What research supports this particular method for this age group, concern, and intended outcome?
- What are the limitations of that research?
- What training and clinical qualifications do you have for the service you are proposing?
- What risks or unwanted changes should we discuss, and how would I contact you about them?
- How will we evaluate changes in daily life alongside the training information?
Measuring something during a session and finding a meaningful change in everyday functioning are separate questions. A different display or a different signal does not settle which approach is appropriate for a person. For a fuller discussion of measurement, see the clinic’s neurofeedback progress-tracking guide.
If you want to ask about Vibrant Life Therapy’s InfraLow approach, contact the clinic with the questions you want answered. A conversation about the actual protocol is more useful than choosing between two broad labels.
