PNV at a glance
Vision: a unique gateway to the nervous system
Neuroscience has shown that around 60% of the brain is involved in vision,* through neural pathways connected to emotional regulation, hormonal function, sleep, attention, memory, and many other essential processes.
The richness and complexity of the visual system help explain why the simple visual exercises used in PNV can influence the overall functioning of the nervous system and help restore its natural regulation.

An effective way to regain your full potential
Nervous system dysregulation is not a disease in itself. You may therefore receive normal results from standard medical examinations while still experiencing significant difficulties.
These functional imbalances are nevertheless very real and can have a major impact on everyday life.
The PNV Assessment can identify specific patterns of nervous system dysregulation, while personalized neurosensory training helps restore more balanced nervous system function.
Building on Georges Quertant’s Psycho-Sensory Culture (CPS)
PNV builds on the principles of Psycho-Sensory Culture (CPS), also known as the Quertant Method (Méthode Quertant), an applied neurophysiological approach developed by Georges Quertant.
His work anticipated many discoveries that have since been supported by modern neuroscience, particularly regarding the role of the brain’s regulatory centers in nervous system function.
PNV is a structured neurosensory training programme based on a progressive sequence of visual exercises designed to help normalize nervous system responses to a wide variety of stimuli that reproduce the demands and stressors of everyday life.
PNV in practice
STEP 1: The PNV assessment
During your assessment, a certified PNV practitioner observes how your nervous system responds to a carefully designed series of visual stimuli presented using a specialized device.
These stimuli reproduce the types of sensory demands encountered in everyday life.
From these objective observations, your practitioner can evaluate your current nervous system functioning, identify possible patterns of dysregulation, and assess their intensity.
The results are then explained to you, together with how they may relate to the everyday challenges and difficulties you experience.
In brief: the PNV Assessment
Understand how your nervous system is currently functioning and whether nervous system dysregulation may be contributing to your difficulties.
Duration: Approximately 90 minutes.
Location: At a PNV Centre.
Rate: Please contact your local PNV practitioner.
Important: The PNV Assessment is not a medical diagnostic tool. Because the method relies on visual stimulation, we also recommend having a routine eye examination with an ophthalmologist and an orthoptist to rule out any underlying visual disorders before beginning training.
STEP 2: Personalized Neurosensory Training
Your practitioner will guide you through a personalized training program designed to gradually adjust your nervous system’s responses to a range of visual stimuli.
As your nervous system becomes more balanced, manifestations progressively diminish and often disappear.
Training is carried out using a dedicated PNV device, at a rate of two 30-minute sessions per week, and a complete program generally lasts several months.
Sessions can take place at a PNV centre. For those who cannot attend regularly, a home-training device is also available to rent.
In brief: the neurovisual training
Learn to regulate your nervous system through personalized training and reduce the manifestations associated with nervous system dysregulation.
Program length: Several months.
Frequency: Two sessions per week (30 minutes each).
Location: At a PNV Centre or at home using a rented PNV device.
Rate: Please contact your local PNV practitioner.
