Tutorials

We are currently working on a new version of this page, expected to be finished during the summer 2015.

Required background

These tutorial pages suppose you are comfortable with the basic concepts of MEG and EEG source imaging. If you're not, we engage you to read some background information, which will quickly help you getting up to speed with this field:

• A non-technical overview of MEG and EEG, with an emphasis on source modeling:
  Canada MEG Consortium

• Slides from a selection of educational courses:
  megcommunity.org

• Reference books:

  • MEG: An Introduction to Methods
    Editors: P Hansen, M Kringelbach, R Salmelin, Oxford University Press, 2010, 448 pages

  • The Oxford Handbook of Social Neuroscience
    Editors: J Decety, JT Cacioppo, Oxford University Press, 2011, 1128 pages
    A draft version of the MEG chapter by Sylvain Baillet can be found here.

• Good practice for conducting and reporting MEG research, Gross et al, Neuroimage, 2013

• You can also ask us to come and organize a training session at your institution, or visit us to obtain training (McGill's Montreal Neurological Institute).

Now you are well equipped to go through the software tutorial, Enjoy!

Get started

The easiest way to get started with Brainstorm is to follow carefully those introduction tutorials. In just a few hours, you will be introduced to the essential features of the application. You will find a report form at the end of each tutorial, please share your comments to help us improve the documentation and the software. To get a quick overview of the software interface, you can watch this introduction video.

If you need a printed version of a page, click on the "print" link at the top-right corner of the page. However, note that those pages are updated with the software, and cannot be kept as long term reference documentation.
