Actuellement, le flux d\u2019informations entre le cerveau et un membre bionique ne se fait que dans un seul sens\u00a0: l’activit\u00e9 des neurones est enregistr\u00e9e \u00e0 l’aide d’\u00e9lectrodes et traduite en commandes, ce qui permet le mouvement du membre robotique. Ce syst\u00e8me manque toutefois de pr\u00e9cision, en raison notamment de l’absence de perceptions sensorielles du membre artificiel. Des chercheurs de l\u2019Universit\u00e9 de Gen\u00e8ve (UNIGE<\/a>) ont d\u00e9couvert qu’il \u00e9tait possible de transmettre cette sensation manquante par stimulation neuronale et que son apprentissage se faisait rapidement.<\/p>\n

Les exp\u00e9riences ont \u00e9t\u00e9 men\u00e9es chez la souris\u00a0: \u00ab Nous avons voulu voir si les souris sont capables d\u2019apprendre \u00e0 contr\u00f4ler un bras bionique uniquement \u00e0 l\u2019aide d\u2019un retour de sensation artificielle \u00bb, explique Mario Prsa, chercheur \u00e0 l\u2019UNIGE et premier auteur de l\u2019\u00e9tude, dans un communiqu\u00e9<\/a>.<\/p>\n

Ces recherches, publi\u00e9es dans le journal scientifique Neuron<\/a>, jettent les bases du d\u00e9veloppement d\u2019une nouvelle g\u00e9n\u00e9ration de neuro-proth\u00e8ses bidirectionnelles. Ce type d\u2019interface pourrait permettre de faire bouger un bras bionique plus rapidement, sentir l\u2019objet touch\u00e9 ou percevoir la pression n\u00e9cessaire pour l\u2019empoigner.<\/p>\n","protected":false},"excerpt":{"rendered":"
