# Jean-Didier Vincent

Jean-Didier Vincent (7 June 1935 – 4 December 2024) was a French neurobiologist and neuropsychiatrist. He was Professor of Physiology at the Faculty of Medicine of the University of Bordeaux II and then at the University of Paris-Sud. From 1991 to 2004 Vincent was Director of the Alfred-Fessard Institute of Neurobiology at the CNRS. He was a member of both the French Academy of Sciences and the French Academy of Medicine since 18 November 2003.

## Biography

Vincent was born on 7 June 1935 in Libourne, located in the Gironde department of Bordeaux. He was the only son of a Freemason wine broker.
He studied in Sainte-Foy-la-Grande (Gironde) at a Protestant college whose master intended him to study literature at the École normale supérieure, then at the Lycée Michel-Montaigne in Bordeaux. His parents, wine brokers and Protestants, encouraged him to undertake medical studies at the École du Service de Santé des Armées de Bordeaux. He majored in physics, chemistry and biology. As an intern in clinical services, he met the neuropsychiatrist Jacques Faure, who encouraged him to do research in this field.
Vincent was a hospital biologist in physiology and functional explorations at the CHRU of Bordeaux (1966-1977), Professor without a chair (1973-1978) and professor of physiology at the Bordeaux Faculty of Medicine (1979-1992). He headed the Inserm 176/CNRS "Neurobiology of Behaviours" unit at the Bordeaux University Hospital (1978-1990) before taking over as Director of the Alfred-Fessart Institute in Gif-sur-Yvette from 1992 to 2003. He was Professor of Physiology at the Faculty of Medicine of Paris Sud, Hospital Practitioner at the Kremlin-Bicêtre Hospital (1992-2006) and Professor at the Institut Universitaire de France, Chair of Neuroendocrinology at the Faculty of Medicine of Paris-Sud, Paris XI University (1994-2004).
In 1988, he signed the appeal to François Mitterrand. He has carried out research in neurobiology in the United States (postdoctoral fellowship at the Brain Institute of the University of California, Los Angeles) and then in France (CNRS, Inserm).
Vincent was President of the National Council of Programmes at the Ministry of National Education from 2002, a member of the CNRS Ethics of Science Committee (COMETS) and the INRA (Institut National de Recherché en Agronomie) Ethics and Precaution Committee for Agricultural Research Applications (COMEPRA). A member of the Executive Board of the Foundation for Political Innovation until 23 January 2009, he has been President of the Association pour l'Université Numérique Francophone Mondiale (UNFM) since October 2005.
Married to Yveline Ricoul and later to Lucy Kukstas, he had five children. Jean-Didier Vincent died on 4 December 2024, at the age of 89.

## Scientific contributions

Vincent contributed significantly to the development of neuroendocrinology, which includes the study of interactions between hormones and the nervous system, the brain being also considered as an endocrine gland. He has a more pessimistic vision than his colleague Boris Cyrulnik about what predetermines human behaviour and believes in the primacy of the biological over reason, stating in 2013 in the film La Possibilité d'être humain : "L'homme est libre, oui, mais en liberté surveillée".
He published numerous books on the theory of biology, for example, Biologie des passions, La Chair et le diable. In his book he defends a dynamic above all sexual dynamics of love (Eros). He lists the sexual practices that are omnipresent in nature and suggests that the notion of women's property was born during the sedentarization of the Neolithic era. It also details the complexity of sexual systems, which are often designed to frame the reproductive rules of each species.
In his book Bienvenue en Transhumanie, he takes a sceptical look at transhumanism, denouncing a lack of morality that is necessary around this radical transformation of the genome. He fears a disconnection between reproduction and sexuality, and that sexuality is virtualized by directly stimulating the affected parts of the brain.

## Polemics
### On Down's syndrome

On 5 October 2012, during the programme La Tête au carré, broadcast on France Inter, a new test likely to diagnose trisomy 21 in early pregnancy was discussed. Vincent defended this prenatal diagnosis, claiming that "Down's syndrome is a poison in a family. "During the programme, Jean-Didier Vincent revisited this statement, which was considered "violent" by host Mathieu Vidard, and withdrew it, calling it an "unfortunate term" but without apologizing. Éléonore Laloux, a young woman with Down's syndrome and spokesperson for the collective Les Amis d'Éléonore, responded to the biologist in 2013 in a video and in March 2014 in an autobiographical book.

### On GMOs

During the same programme, Vincent defended the firm Monsanto and made the following comments: "we must use GMOs", "it has rendered great services to agriculture", "it has increased productivity."

### Conviction

On 12 February 2008, during the television show Ce soir ou jamais, he said about Jean-Marie Le Pen: "We knew him as the white wolf, he was a bastard", and added: "he probably committed crimes, but I can't say it on the air". On 28 May 2009, the Paris Court of Appeal found him guilty of insult (first sentence) and defamation (second sentence), and sentenced him to a suspended fine of €1,500 and €4,000.
