L\u2019interface cerveau-machine (BCI), une technologie sans fil, connecte le cerveau \u00e0 la moelle \u00e9pini\u00e8re, traduisant les intentions de mouvement en actions physiques. Gert-Jan Oskam, parapl\u00e9gique apr\u00e8s un accident de v\u00e9lo, a retrouv\u00e9 la capacit\u00e9 de marcher, de monter des escaliers, et m\u00eame de se tenir debout au comptoir d’un bar.<\/p>\n

Pour ce faire, deux implants \u00e9lectroniques ont \u00e9t\u00e9 utilis\u00e9s : l’un dans la r\u00e9gion c\u00e9r\u00e9brale contr\u00f4lant les mouvements des jambes, et l’autre sur la moelle \u00e9pini\u00e8re qui contr\u00f4le les m\u00eames mouvements. Le dispositif c\u00e9r\u00e9bral, le WIMAGINE\u00ae<\/a>, d\u00e9velopp\u00e9 par CEA, d\u00e9code les signaux \u00e9lectriques g\u00e9n\u00e9r\u00e9s par le cerveau lorsqu’on pense \u00e0 marcher. Parall\u00e8lement, un neurostimulateur est connect\u00e9 \u00e0 un champ d’\u00e9lectrodes positionn\u00e9 sur la moelle \u00e9pini\u00e8re.<\/p>\n

L\u2019intelligence artificielle joue un r\u00f4le crucial en d\u00e9codant les intentions de mouvement en temps r\u00e9el \u00e0 partir des signaux c\u00e9r\u00e9braux, puis en les convertissant en stimulations \u00e9lectriques de la moelle \u00e9pini\u00e8re. Ces stimulations activent \u00e0 leur tour les muscles des jambes pour produire le mouvement d\u00e9sir\u00e9. L’ensemble du syst\u00e8me fonctionne sans fil, permettant une mobilit\u00e9 autonome.<\/p>\n

Possibilit\u00e9s futures et commercialisation de l’interface cerveau-machine<\/h4>\n

Au fil du temps, gr\u00e2ce \u00e0 l\u2019usage r\u00e9p\u00e9t\u00e9 de la BCI, Gert-Jan a regagn\u00e9 certaines fonctions neurologiques perdues. M\u00eame lorsque la BCI \u00e9tait d\u00e9sactiv\u00e9e, des am\u00e9liorations sensorielles et motrices notables \u00e9taient observ\u00e9es, laissant pr\u00e9sager la formation de nouvelles connexions nerveuses.<\/p>\n

Enfin, les chercheurs envisagent d\u2019appliquer cette technologie \u00e0 la restauration des fonctions des bras et des mains, ainsi qu’\u00e0 d’autres cas de paralysie, comme ceux r\u00e9sultant d\u2019un accident vasculaire c\u00e9r\u00e9bral. L’entreprise ONWARD Medical<\/a>, avec l’EPFL et le CEA, travaille \u00e0 d\u00e9velopper une version commerciale de la BCI avec le soutien du Conseil Europ\u00e9en de l\u2019Innovation.<\/p>\n","protected":false},"excerpt":{"rendered":"
