Séminaire "New clinical applications of Brain Computer Interfaces" le 19/11/2015 à 15h00

Nous aurons le plaisir d’accueillir les 19 et 20 novembre au LTSI, deux ex-doctorants du laboratoire : Mario CHAVEZ (Chercheur au CNRS) et Xavier NAVARRO (Post-Doctorant), qui travaillent à l’Institut du Cerveau et de la Moelle Epinière (ICM) à Paris. Dans le cadre de leur visite, Mario et Xavier nous présenteront, le jeudi 19 novembre à 15h00 dans la salle de réunion, 5ème étage, ses travaux sur les «  Nouvelles applications cliniques des interfaces cerveau-machine ».

Abstract: In this seminar, we will introduce our research and developments in brain computer interfaces (BCI), making special emphasis on new clinical applications in reanimation. We will describe the "brain ventilator interface" (BVI), a new class of applications for BCI: monitoring of respiratory states from EEG signals. This BVI  is designed to detect respiratory discomfort in subjects on mechanical ventilation. The BVI exploits the cortical activation provoked by the inspiratory compensation when the patient and the ventilator when the last one is not properly tunned. Using a semi-supervised approach and Riemannian geometry of EEG covariance matrices allows effective classification of respiratory states. The BVI was validated on healthy subjects under different respiratory states. Results evidenced that classification performances are significantly improved using EEG signals compared to traditional detection based on air flow.
