Sorry, this entry is only available in French. Les ultrasons transforment le domaine de la neuroimagerie, grâce aux avancées technologiques réalisées au cours de la dernière décennie par le laboratoire Physique pour la Médecine (Inserm, ESPCI Paris – PSL, CNRS). L’introduction, en 2009, de l’imagerie fonctionnelle ultrasonore (fUS) a doté les neuroscientifiques d’une technologie unique […]
Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye… You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research by scientists from Inserm, CNRS and Université de Montpellier at the Structural Biology Center in Montpellier . This highly innovative “nano-robot” should enable closer study of the mechanical forces applied at microscopic levels, which are crucial for many biological and pathological processes.
As with many of the body’s functions, pain intensity is controlled by our internal clock. This is what a team of Inserm researchers at the Lyon Neuroscience Research Center (Inserm/Université Claude Bernard Lyon 1/CNRS) has recently discovered. They show that pain oscillates over 24 hours with a peak at night and a decrease in the afternoon, regardless of the sleep-wake cycle or any external stimulation. This discovery could lead to new approaches to how we treat pain.
Our ability to understand the syntax of complex sentences is one of the most difficult language skills to acquire. In 2019, research had revealed a correlation between being particularly proficient in tool use and having good syntactic ability. A new study has now shown that both skills rely on the same neurological resources, which are located in the same brain region. Furthermore, motor training using a tool improves our ability to understand the syntax of complex sentences and – vice-versa – syntactic training improves our proficiency in using tools.
What if a few minutes of interaction with a chatbot could effectively address vaccine concerns? In an article published in the Journal of Experimental Psychology: Applied (28 October 2021), researchers from the CNRS, INSERM, and ENS-PSL show that such an interface is indeed capable of swaying the vaccine-hesitant.
Pour les individus en insuffisance rénale terminale, la greffe du rein est le meilleur traitement. Compte tenu de la pénurie d’organes dans le monde, le rejet et la perte du greffon sont considérés comme de véritables échecs. Dans une étude publiée le 27 octobre 2021 dans la revue The Lancet Digital Health, une équipe de recherche présente ses travaux qui ont permis de mettre au point un nouveau modèle de prédiction de la perte du greffon avec des performances de prédiction encore jamais atteintes.
For the past 30 years, it was thought that the brain – responsible for motor control – worked to continuously compensate for the effects of gravity. In an initial study in 2016, the researchers had suggested that our brains use gravity to minimize the effort our muscles have to make. Those results were recently confirmed by new experiments conducted in collaboration with New York University on non-human primate models and humans.
Le Centre Hospitalier Universitaire de Bordeaux et le centre de recherche Inserm Bordeaux Population Health à Bordeaux publient les résultats de leur étude sur les appels au SAMU centre 15 de la Gironde sur l’année 2020. Pour classer ces appels, les chercheurs ont fait appel à une technologie issue d’une avancée très récente dans le domaine de l’intelligence artificielle qui porte le nom de « Transformer ».
Huntington’s disease is a hereditary disorder that causes degeneration of the neurons involved in cognitive, motor and psychiatric functions. While existing treatments address the symptoms and relieve certain aspects of the disease, they cannot alter its course.
Les personnes atteintes de neuropathie optique héréditaire de Leber perdent la vue dès l’adolescence avec un déclin soudain au niveau des deux yeux, jusqu’à la cécité. Alors que les options de traitements étaient jusqu’ici très limitées, des chercheurs à l’Institut de la Vision ont conçu une approche de thérapie génique pour ces patients.
