In anorexia nervosa patients, the weight loss through lack of food is accompanied by fatigue and reduced physical capacity. Yet despite this they often continue to perform intense physical activity which contributes to that weight loss.

Charcot-Marie Tooth disease is the most common hereditary neurological disease in the world. It affects the peripheral nerves and causes progressive paralysis of the legs and hands. No treatment is currently available to fight this disease, which is due to the overexpression of a specific protein.

Lorsque nous rêvons, nous sommes à première vue coupés du monde, incapables de recevoir des informations de l’environnement et d’y répondre. Pour la première fois, une collaboration entre des chercheurs de l’Inserm, de l’AP-HP, de Sorbonne Université et du CNRS avec plusieurs groupes américains, allemands et néerlandais, montre qu’une communication à double-sens, de l’expérimentateur vers le rêveur et vice-versa est possible au cours du rêve.

Are our emotions innate or are they the product of our culture and environment? This question has long been the subject of debate in the field of neuroscience. Researchers provide robust clinical data in favor of the second hypothesis. Their work suggests that our ability to know and recognize emotions is built up gradually and depends on our knowledge of language.

Dysfunctions of ion channels – or channelopathies – in the brain are today associated with more than 30 neurological diseases such as epilepsy or cerebellar ataxias. A study conducted at the Brain Institute (Sorbonne University / Inserm / AP-HP / CNRS) identified a new cerebral channelopathy originating from dominant mutations in the KCNN2 gene, encoding the SK2 ion channel.

L’anorexie mentale est un trouble psychiatrique très sévère qui touche jusqu’à 4% de la population. De plus, c’est la maladie mentale avec le plus fort taux de mortalité (1% des personnes atteintes en meurent chaque année).
