History of PNV®:
PNV® Neuro Visual Training stems from the Quertant Method, developed by Georges Quertant, formerly known as CCPS or Cerebro Psycho Sensory Culture (Culture Cérébro Pyscho Sensorielle). The Quertant Method was endorsed/approved by France’s Ministry of Health in 1942 and Georges Quertant was made Chevalier de la Légion d’honneur (Knight of the Legion of Honor) for the Department of Education / in National Education in 1952 for having created it.
Similarly to the Quertant Method, PNV® aims to regulate the brain’s nerve centers using optical devices. This process allows for the elimination of most functional disorders, and also gives one the means to recover a high-performance intellectual potential, a better discernment and regulation of sensitivity, and an inner tranquility.
Hélène van Seters-Husson created PNV® Neuro Visual Training and while its founding principles and theory remain faithful to the Quertant Method, its practice differs greatly in its human and educational approach and made much more accessible.
Who was Georges Quertant (1894-1964)?
Georges Quertant was a brilliant 20th century researcher. He was a conductor, researcher and pedagogue, and developed his Psycho Sensory Culture (or Quertant Method) over more than 20 years. Having observed the effects of music on his brother’s psychiatric patients, he delved into his investigation of how the pathologies he encountered could be positively affected by music. Limited by his era’s audio recording and reproduction technologies, he then moved on to focus on vision, touch and phonation/speech.
A great deal of work went into this research. His mentor Claude Bernard – renowned 19th-century physiologist – inspired him to devise a tool that would allow for the sensory system to be used to access the “nerve organs” for their rehabilitation. His technique was subsequently developed alongside children in difficulty and adults suffering from numerous, varied functional disorders.
The vision problems of his daughter, Marguerite Quertant (1923-2011), led him to investigate the visual dimension exhaustively and thus rehabilitate her severe strabismus. Ms. Quertant was profoundly grateful and subsequently devoted her entire life to her father and his method.
While Georges Quertant developed a multimodal tool (sight, hearing, touch, speech/phonation) with considerable/meticulous scientific rigor, he only passed on the visual modality/method to his daughter. Nowadays CPS Quertant is no longer sensory but solely visual.
It relies on rehabilitative devices called diploscopes, created by Dr. Armbruster in 1909 and which brought the necessary materials for the visual dimension of Quertant’s psycho sensory culture.
Upon his death he had trained only his daughter, who in turn only trained a handful of people over the course of her life.
Hélène van Seters-Husson relates her encounter with this remarkable method and her personal choices:
“Meeting Marguerite Quertant was momentous for me. She was such a charismatic, extraordinary character and was so passionate about her father and his work. She lit a fire in me that still burns just as bright and powerful 15 years later. Upon her death in 2011, she passed/handed down the “Méthode Quertant” name to Brigitte Boni de Monseignat who is now in charge of the project.
I opted to develop and advance the practice by making different choices, and thus decided to create PNV®. PNV® rids itself of outdated models and enters into the sharing era and modern teaching methods. It enters into a world in transition, choosing collaboration and exchange. The 4in1 was conceived so as to be more affordable, less cumbersome and therefore more accessible to all, allowing for new possibilities.
I hope to thereby participate in the blossoming and success of such a deserving approach, now more than ever, in a world where our nervous system is overstimulated.”
