Comme de très nombreuses fonctions de l’organisme, l’intensité de la douleur est contrôlée par l’horloge circadienne interne. C’est ce que vient de découvrir une équipe de chercheurs et chercheuses de l’Inserm au sein du Centre de recherche en neurosciences de Lyon (1). Selon les résultats de cette étude, l’intensité de

Certains biais cognitifs, tels que les biais d’optimisme et de confirmation, contamineraient nos mécanismes mentaux les plus simples. Une étude inédite ouvre la voie à de nouvelles pistes de recherche qui permettraient d’affiner notre compréhension des biais et processus cognitifs liés à l’apprentissage, et notamment celui dit « par renforcement

De nombreuses pathologies du système nerveux central sont associées à une mort de neurones sans que le cerveau ne soit capable de les régénérer. Ce phénomène est notamment observé dans la maladie de Parkinson ou d’Alzheimer, suite aux accidents vasculaires cérébraux mais aussi dans certaines formes d’épilepsies. Comment régénérer ces

Le cerveau révèle petit à petit les mystères de son fonctionnement. Outre l’étude des neurones, les chercheurs et chercheuses s’intéressent de plus en plus au rôle d’autres types de cellules du système nerveux qui aident les neurones dans leurs tâches quotidiennes. Une étude conduite par des scientifiques de l’Inserm, du

Au XIXe siècle, on mesurait les crânes et les cerveaux pour justifier la hiérarchie entre les sexes, les races et classes sociales. Le XXe siècle découvre et admet comme critères modernes les tests cognitifs, l’imagerie cérébrale et les gènes.  Que sera le XXIe siècle, depuis la découverte de la plasticité

On a longtemps considéré les émotions comme des expériences biologiques innées et universelles, bien distinctes les unes des autres. Mais sont-elles vraiment innées ou bien sont-elles le produit de notre culture et de notre environnement ? Cette question fait depuis longtemps l’objet de débats dans le domaine des neurosciences. Des

We're not on Planet of the Apes, but almost. Indeed, scientists have just implanted a gene specific to man that would be responsible for the size of our brain and our so-called advanced cognitive abilities. The result is so spectacular that research was immediately stopped.

The senators are currently examining the bioethics bill, a text voted in first reading by the National Assembly in October 2019. This bill brings new elements in the framework of research in several innovative areas of biomedicine, including the neurotechnology which is booming.

Should we be afraid of memory implants? A recent study echoed by UP' reports possible cyber attacks on our memory. Jean-Gabriel Ganascia, a researcher in artificial intelligence, provides a forum that puts the legitimate fears we may have in their rightful place. Remote appropriation

The brain is a constantly evolving organ and its functioning raises many questions. For example, scientists are working to discover how memories are created in the brain so that they can be targeted, restored and enriched with implants, and the necessary technologies already exist under

Did you say "nano"? It's often difficult to imagine a grain of matter at the nanoscale: a billionth of a metre. To get an idea of this, let's point out that the size ratio between planet Earth and an orange is similar to that between an orange

Violence, aggressiveness, attacks on moral order, crime, terrorism... Could all these deviant behaviours have their origin in the brain? To find out, would the method of choice be MRI imaging, which now makes it possible to see the brain at work without having to open the skull? Certainly neuroscience is bringing

In the 19th century, Cesare Lombroso founded scientific criminology. He claimed to identify criminals by the anatomical features of the face and skull. Science came to the rescue of justice... Where are we in the 21st century? The same quest still drives some biologists, particularly in the United States...

Researchers at the Montreal Neurological Institute and Hospital of McGill University's Montreal Neurological Institute and Hospital have proven that it is possible to intensify or attenuate the pleasure derived from music, as well as the irresistible desire to hear more, by stimulating or deactivating certain brain circuits. An interesting approach to addiction treatment

Could the microbial community in our nose influence our food choices? Men or women, young or old, we are all colonized by one to two kilos of micro-organisms. These bacteria, viruses and fungi, present inside and outside our bodies, are grouped together under the term "bacteria".

In order to imagine and lead into a different future, our intelligence must be mobilized, desire must be in the game, fear must not have the power, anger must be used for progress and not for violence, sadness and distress must be used to take care of the sick and the disabled.

The right to cognitive freedom, the right to mental privacy, the right to mental integrity and the right to psychological continuity are the four new laws proposed by researchers to protect themselves from a future that will be dominated by neuroscience. New rights of

The experiment was conducted on the brains of frogs. Even tadpoles, to be precise. It involved exposing embryos of the species Xenopus laevis to a mixture of chemicals comparable to that found in the amniotic fluid of most pregnant women. Of these, the most

In honor of Brain Week, which is being held throughout France, I propose that you take the time to ask yourself the question of the interest of neuroscience for management. Throughout life, we are aware that we have a heart, lungs... which we know

The neurosciences' view of an initiatory journey: What happens to the brain of the cyclist who sets off on a solo circumnavigation of the world? She had just turned twenty-seven, found the time long, the environment too narrow. Béatrice MAINE then imagined cycling around the world.
