Understanding the Differences Between Linear and Non-Linear Neurofeedback

Neurofeedback is a powerful tool for enhancing brain function, but not all neurofeedback systems operate the same way. There are two primary approaches: linear neurofeedback and non-linear neurofeedback. While both methods aim to support brain optimisation, they take distinct paths to achieve this goal.

Feature NeurOptimal® (Non-Linear Neurofeedback) Linear Neurofeedback
Expertise Required No expertise required. Expertise needed throughout the process.
Diagnosis No diagnosis needed. Diagnosis required.
Signal Integrity Check No check required; NeurOptimal® automatically removes unwanted signal. Careful hookup needed to minimize impedance, often involving scrubbing site. May use impedance meter to confirm signal integrity.
Approach Training, not treatment; no protocols. Use of treatment protocols.
Session Monitoring No monitoring needed; AutoNavigation takes care of everything. Careful monitoring of session while it is occurring; parameters may need to be changed.
Control Over Brain Activity Does not tell the brain what to do. Uses augment frequencies and suppress frequencies, instructing the brain what to do.
Feedback Scope Offers feedback on 20 different “targets” at once. Works with limited frequency bands.
Training Approach No states are trained. Training is state-based.

Why is This Important?

  • Expertise, if you can find it, can be expensive.
  • You shouldn’t need something to be wrong with you to train your brain.
  • You do not need to be an expert to get expert training. Your diagnoses may require contradictory protocols; your practitioner must get the choice right.
  • Effortless sessions.
  • If a practitioner makes the wrong decision, effects can be very unpleasant.
  • Limited frequency bands can produce side effects. Training with limited bands = limited training.
  • NeurOptimal®’s 20 targets naturally balance each other. Positive effects are seen in many areas of life.
  • Excess training in any state can lead to unwanted side effects.

Linear Neurofeedback

A clinician may focus on reducing theta wave activity in a client with ADHD to enhance focus, reinforcing desired brainwave patterns. However, this narrow approach requires extensive practitioner expertise to avoid unintended consequences.

Non-Linear Neurofeedback

A NeurOptimal® system provides real-time feedback whenever the brain experiences a slight shift in activity, allowing it to self-regulate toward a balanced state without enforcing specific patterns. Because it works across all frequencies, every client benefits from a comprehensive, naturally balancing approach.

Which Approach is Right for You?

Both methods have their applications. However, non-linear neurofeedback offers a gentler and more adaptable approach, giving the brain the freedom to optimize itself naturally without the risk of overtraining or unwanted side effects. Additionally, unlike linear neurofeedback, NeurOptimal® does not require years of practitioner training—every brain has its innate intelligence and can self-correct when provided with the right information.

NeurOptimal®’s unique Dynamical Thresholding® and ZenModes offer an unprecedented level of safety and natural transformation, allowing the brain to reorganise itself seamlessly, no matter the severity of symptoms. By working with the brain’s own intelligence rather than imposing external goals, NeurOptimal® provides a truly revolutionary approach to neurofeedback.
