Inverse problems in brain imaging and multimodal data fusion
Montreal, CANADA, August 24-29, 2009
Organizers: Christophe Grova(McGill), Sylvain Baillet (Med. College of
Wisconsin), Jean-Marc Lina (Ecole de Technologie Superieure, CRM)

Sylvain Baillet, Jean-MarcLina and myself are organizing a workshop entitled
"Inverse problems in brain imagery and multimodal data fusion". This
workshop supported by the "Centre de Recherche en Mathématiques" de
l'Université de Montréal ( will last  5 days in
Montreal from the 24th to the 29th of August 2009
The diversity of non invasive imaging devices (MRI, EEG, MEG, Near Infrared
Spectroscopyl) allows one to explore the brain dynamics provided there
exists a mathematical framework that encompass this multimodality and the
complexity of the inherent sources of the cerebral signals. Despite a
general agreement about the source modelling, many mathematical strategies
have been elaborated in order to solve the inevitable ill-posed inverse
problem.. What are the common features between those approaches? What are the
mathematical frameworks the most appropriate for handling simultaneous
measurements from different modalities? What are the best approaches for
estimating both spatial and temporal brain activities?

The workshop will consist in full 3-hours invited lectures followed by more specific
presentations and one poster session.

Participants interested in presenting a contributed talk or a poster are
invited to submit an abstract before the 15th of July 2009.

Participants interested in attending, the registration is now open, places
are limited
