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.

Cette année 2020 sera marquée dans les annales comme époque extraordinairement difficile à vivre. Les crises s’empilent les unes sur les autres —sanitaire, économique, sécuritaire— sur fond d’écoanxiété liée à notre survie sur une Terre surchauffée et malmenée par l’activité des hommes. Autant de raisons qui expliquent les bouffées de

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.

In the 19th century, skulls and brains were measured to justify the hierarchy between sexes, races and social classes. In the 20th century, cognitive tests, brain imaging and genes were discovered and accepted as modern criteria. What will the 21st century be like, since the discovery of plasticity?

The information was published in China in the Beijing National Science Review on March 27 and revealed to the world by the MIT Review today, April 10. Chinese geneticists are believed to have succeeded in introducing copies of a human gene suspected of playing a role in the development of the brain of monkeys.

Genopole, Télécom SudParis et l’Université d’Évry accueillent une nouvelle équipe scientifique pour explorer la complexité du cerveau. L’équipe s’est installée à Évry grâce au dispositif d’aide à la recherche de Genopole, au soutien de l’Université d’Évry et aux équipements dédiés à l’innovation du centre ETOILE, récemment ouvert sur le

In France alone, Alzheimer's disease affects one million people, mobilises two million carers and costs the community €20 billion. But there is no cure. And yet, scientists regularly announce discoveries and experiments that quickly prove to be ineffective. The dream of offering a treatment

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

The American startup Netcome came up with this bizarre idea. To vitrify the brain, by a patented process, to preserve, in working order, the neuronal connections. Then preserve it for an indefinite number of years, until we know how to download it onto a medium capable of re-functioning the

A new type of brain implant that works much like a pacemaker could increase memory by 15%. Neural implants that claim to stimulate memory function are not new, but an innovative approach to the problem has led to a device that sends electrical impulses to help the

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

The field of neuroscience has undergone a veritable revolution over the last thirty years thanks to the arrival of new imaging and investigation tools that have made it possible to explore brain structures in great detail and to reveal the electrical and biochemical functioning of the various brain cells.

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.

Bad memories often taint the mind. For some, victims of post-traumatic stress, they are so violent that they resist treatment and prevent a normal life. A neuroscientist, working on the mechanisms of learning, accidentally discovered that some bad memories can be erased forever. A drug

Une étude réalisée par des scientifiques britanniques vient d’être publiée dans les Actes de l’Académie Nationale des Sciences, et elle fait froid dans le dos. Des nanoparticules toxiques liées à la pollution de l’air viennent en effet d’être trouvées « en quantité abondante » dans les tissus du cerveau ; elles pourraient être

Le corps est devenu un terrain de jeu. On connaît des artistes comme l’australien Stelarc qui s’est fait greffer une oreille sur le bras gauche ou des scientifiques comme Kevin Warwick qui s’est doté d’implants électroniques. Ces cas isolés deviennent légion avec l’engouement pour la biologie de garage et des

What is the memory of the future? It is the memory that projects us into the future. This prospective memory has the particularity of needing information acquired in the past or the present - which amounts to the same thing - so that we can imagine hypotheses about probable futures. But..,
