Objectives:
Montreal Neurological Institute, McGill University, 3801 University st., Montréal, QC
This two-day training workshop is an initiative of the Canada MEG Consortium (CMC) to promote
and disseminate magnetoencephalography (MEG) as a brain imaging technique, in Canada an
beyond. The CMC regroups the 6 Canadian MEG centres as a joint academic network and MEG
task force for access, education, shared expertise and instrument and software resources about
MEG, for neuroscience and neuroimaging investigators.
This first training workshop has the following objectives:
1) To educate investigators who are new to brain imaging, and to MEG in particular about the
possibilities offered by MEG as a brain functional imaging technique;
2) To expose the conceptual foundations of MEG signal analysis and imaging;
3) To clarify the typical workflow for MEG data analysis
4) To provide a first, elementary hands-on experience with data acquisition and analysis
5) To incite investigators to consider MEG as the modality of choice for their research projects.
Brainstorm hands-on training course: The CMC training will be immediately followed by a Brainstorm hands-on
training course (joint or separate registration required), where attendees will be able to extensively
go through multiple practical aspects of MEG signal analysis and source imaging, using Brainstorm
(attendees are encouraged to bring their own laptops; PCs will also be available).
Targeted audience: Investigators (faculty, research associates and students) new to neuroimaging or to MEG in
particular, willing to learn about MEG as a potential modality of choice for their clinical or cognitive
neuroscience studies. An emphasis will be made on the complementarity of MEG with functional
MRI (fMRI) and EEG.

Brainstorm MEG/EEG Imaging Course
Saturday, November 19, 2011
Organized by:
The MEG Program @ McGill
Location:
de Grandpré auditorium
3801 University St.
Montreal Neurological Institute
McGill University
Montréal, QC
Objectives: We are opening a new software course series dedicated to the training of investigators with the
utilization of Brainstorm, a comprehensive academic software suite for the processing and visualization of MEG
(magnetoencephalography) and EEG data, with an emphasis on functional brain imaging.
The course will consist of a one-day hands-on session, with the primary objective of getting new users familiar
with the software features, in coordination with their research questions. The goal is to help Brainstorm users
reach maximum productivity with their experimental data and learn to identify and use the tools who are the most
able to address their research needs.
Targeted audience:
Investigators (faculty, research associates and students) using MEG and/or EEG in their experimental research,
with a strong interest in imaging neural sources of brain activity from scalp recordings.
Registration:
CMC + Brainstorm course (3 days) $45 (students and post-docs); $75 (faculty)
CMC 2-day workshop only $30 (students and post-docs); $45 (faculty)
Brainstorm course only $30 (students & post-docs) ; $45 (faculty)
Includes coffee breaks and course material (slides)
Requirements:
All attendees must bring and use their own laptop during the hands-on training, with Matlab 2007 or later
version installed. Alternatively, PC users can use an executable version of BrainStorm, which does not require
Matlab. Mac users can also run this executable version through Wine or similar PC emulation program (please
contact francois.tadel@mcgill.ca for technical assistance, prior to the session).
