Paris, FranceHost: Dr. Richard LeahyAbstract:Among the many possible ways to explore brain functions, electromagnetic brain mapping has unique time resolution at the millisecond scale. Measures consist of electric and magnetic signatures of neural activations picked at the scalp level using the techniques of electroencephalography (EEG) and magnetoencephalography (MEG) respectively. The inverse route from surface data to estimates of neural activity can take many paths that draw on a large variety of signal and image processing approaches and statistical analysis tools. Given the excellent time resolution of the resulting image sequences, another important aspect concerns multidimensional data mining issues in space, time, frequency and coupling indices of neural assemblies.This talk is a brief introduction to the potentials of electromagnetic brain mapping from the electrical engineering and integrative neuroscience point of views. Examples will be discussed essentially from sensori-motor studies and clinical applications such as epilepsy.Biography:Sylvain Baillet graduated in Applied Physics from the Ecole Normale Supêrieure, Cachan and in Electrical Engineering from the University of Paris, in 1998. From 1998 to 2000 he was a Research Associate with the NeuroImaging Group at the Signal and Image Processing Institute, University of Southern California, Los Angeles with Prof. Richard M. Leahy. He is now the head of the Brain Imaging group at the Cognitive Neuroscience & Brain Imaging Laboratory, with the Centre National de la Recherche Scientifique (CNRS) and La Salpêtrière Hospital, Paris.His research interests focus on confronting methods and models to experimental challenges in Neuroscience (visuo-motor coordination) and Neurology (epilepsy & stroke).
