What is neurofeedback & PNEI?

Neurofeedback helps the brain to cope better with stress, stimuli, and changes. At Brain-Fit, we combine NeurOptimal® neurofeedback with PNEI for a comprehensive approach focused on more calm, focus, recovery, and resilience.

  • Real-time feedback for the brain's self-regulation
  • Attention to the brain, nervous system, hormones, immune system and lifestyle
  • Often chosen for stress, burnout, sleep problems, ADHD, PCS and Post-COVID

Neurofeedback detects sudden instability in brain activity and informs the brain about it, by means of a brief interruption in sound. This interruption causes your brain to be jolted awake. This allows you to make the brain ‘aware’ of the activity it was engaged in and enables it to choose a different path.


This happens again and again until your brain has optimally corrected itself. You'll notice this through, among other things, sleeping better, being less stressed, experiencing less anxiety, and being able to focus better. This allows you to experience the joy of an easier life, despite the challenges that come your way daily.


You can compare this process to an aeroplane going off course due to turbulence. This costs a lot of energy. Through corrections by the pilot, the aeroplane gets back on the right course and the aircraft can fly peacefully to its destination again.

PNEI (Psycho-Neuro-Endocrino-Immunology) is the science that deals with the relationships and connections between behaviour, the brain, the nervous system, the immune system, and hormones.

Neurotransmitters, important chemical communication streams in your body, are central to the theory. The poor or non-functioning of one or more systems (often the case with chronic complaints) can have a disruptive effect on the other systems.

From a PNEI perspective, by completing the Neuro-4 Profile test, we examine whether your brain (which ultimately controls all systems) is receiving the correct fuel and if neurotransmitters can function properly.

Neurofeedback & PNEI in brief

At Brain-Fit, we use NeurOptimal® neurofeedback and PNEI to support the brain and body in recovery, balance and resilience.

  • Neurofeedback gives the brain real-time information about its own activity.
  • When there is instability in brain activity, the sound is briefly interrupted.
  • The short break helps the brain to recalibrate itself.
  • The training is non-invasive: nothing is added to or imposed upon the brain.
  • NeurOptimal® works without diagnostic protocols, but trains the brain's self-learning ability.
  • PNEI investigates the collaboration between the brain, nervous system, hormones, immune system, and behaviour.
  • With the Neuro-4 profile test, we gain a better understanding of resilience, stress load, and potential imbalances.
  • The combination of neurofeedback and PNEI makes Brain-Fit's approach broader than just brain training.
  • Many clients choose Brain-Fit for stress, burnout, sleep problems, concentration difficulties, anxiety, concussion (PCS) and Post-COVID.
