Conférencier: Mohamad Sawan , Département de génie électrique, École Polytechnique de Montréal
Lieu: UQAM, Pavillon Kennedy, PK-5115 ,
Date et heure: mercredi le 13 février 2013 de 13:30 à 15:30

Résumé: Emerging Brain-Machine Interfaces for diagnostic and recovery of neural vital functions are promising alternative to study neural activities underlying cognitive functions and pathologies. This talk covers circuit techniques and Microsystems intended for intracortical neurorecording and neurostimulation. Special attention will be paid to multidimensional design and implementation challenges such as power management, low-power circuit design, high-data rate communication modules, small-size and low-weight devices, and reliable short distance wireless energy and data transmission will be described. Also, spike recording and seizure detection through large arrays of electrodes will be introduced. Case studies of continuous EcoG recording intended for learning about the intracortical vision mechanism, and onset detection of epileptic seizures will be described. In addition, microstimulation strategies in the primary visual cortex, which is intended to recover vision for the blind through multisite large arrays of microelectrodes will be reported. Finally, Lab-on-chip (LoC) based neurotransmitters detection, manipulation and characterization intended for diagnostic purposes to locate dysfunctions at the level of cells interconnections will be summarized.
