Introduction

Brainstorm is a collaborative, open-source application dedicated to the analysis of brain recordings:
MEG, EEG, fNIRS, ECoG, depth electrodes and multiunit electrophysiology.

Our objective is to share a comprehensive set of user-friendly tools with the scientific community using MEG/EEG as an experimental technique. For clinician-scientists and researchers, the main advantage of Brainstorm is its easy and intuitive graphic interface, which does not require any programming knowledge. We are also putting the emphasis on practical aspects of data analysis (e.g., with scripting for batch analysis and intuitive design of analysis pipelines) to promote reproducibility and productivity in MEG/EEG research. Finally, although Brainstorm is developed with Matlab (and Java), it does not require users to own a Matlab license: an executable, platform-independent (Windows, MacOS, Linux) version is made available in the downloadable package. To get an overview of the interface, you can watch this introduction video.

Since the project started by the end of the 1990's, our server has registered more than 38,000 users, contributing thousands of scientific publications.

We are happy to provide comprehensive documentation via online tutorials and data, and support through a user forum to help you learn how to use Brainstorm. We also deliver in-person and online courses: consult our training pages for upcoming opportunities to learn to use Brainstorm better and faster.

Finally, browse the What's new page for staying on top of Brainstorm news and updates and Like us on Facebook to stay in touch. We hope you enjoy using Brainstorm as much as we enjoy developing and sharing these tools with the community!

Support

This software was generated primarily with support from the National Institutes of Health under grants R01-EB026299, 2R01-EB009048, R01-EB009048, R01-EB002010 and R01-EB000473.

Primary support was provided by the Centre National de la Recherche Scientifique (CNRS, France) for the Cognitive Neuroscience & Brain Imaging Laboratory (La Salpetriere Hospital and Pierre & Marie Curie University, Paris, France), and by the Montreal Neurological Institute to the MEG Program at McGill University.

Additional support was also from two grants from the French National Research Agency (ANR) to the Cognitive Neuroscience Unit (PI: Ghislaine Dehaene; Inserm/CEA, Neurospin, France) and to the ViMAGINE project (PI: Sylvain Baillet; ANR-08-BLAN-0250), and by the Epilepsy Center in the Cleveland Clinic Neurological Institute.

Brainstorm is a collaborative, open-source application dedicated to  magnetoencephalography (MEG) and electroencephalography(EEG) data  analysis ('''visualization, processing and advanced source modeling''').

{{attachment:brainstorm_banner.gif}}

Our objective is to share a comprehensive set of user-friendly tools  with the scientific community using MEG/EEG as an experimental  technique. For physicians and researchers, the main advantage of  Brainstorm is its rich and intuitive graphic interface, which does not  require any programming knowledge. We are also putting the emphasis on  practical aspects of data analysis (e.g., with scripting for batch  analysis and intuitive design of analysis pipelines) to promote  reproducibility and productivity in MEG/EEG research. Finally, although  Brainstorm is developed with Matlab (and Java), it does not require  users to own a Matlab license: an executable, platform-independent''' ''' (Windows, MacOS, Linux) version is made available in the [[Download|downloadable package]].

Since the project started by the end of the 1990's,  our server has registered more than 6,000 software downloads and about  500 users are actively updating the software. See our [[Pub|reference page]] for a list of published studies featuring Brainstorm at work!

The  best way  to learn how to use Brainstorm, like any other academic  software, is to  benefit from local experts. However, you may be the  first one in your  institution to consider using Brainstorm for your  research. We are happy  to provide comprehensive [[http://neuroimage.usc.edu/brainstorm/Tutorials|online documentation]] and support through[[http://neuroimage.usc.edu/forums|our forum]] but there is nothing better than a [[Training|course]] to make your learning curve steeper.
