| = Introduction = !BrainStorm is an integrated free Matlab toolbox dedicated to Magnetoencephalography(MEG) and Electroencephalography(EEG) data visualization and processing. Our intention is to make a comprehensive set of tools available to the scientific community involved in MEG/EEG experimental research. == What you can do with BrainStorm == * Import MEG / EEG from the most popular file formats [[FileFormats|(list here)]] * Data visualization: * Various time series displays * Data mapping on the head surface * Generate slides and animations * Channel selection * Data filtering * 3D surface renderin * MRI visualization and coregistration: * Import MRI scans, from most of the existing file formats ([[FileFormats|list here]]) * Co-registration with the MEG/EEG coordinate system * Volume rendering * Forward modeling: * Single sphere method * Overlapping spheres method * Realistic head models using BEM and FEM * Group analysis: * Registration of individual brains on the MNI "Colin27" brain * Statistical analysis (t-tests, permutations) == What you cannot do with BrainStorm == * Pre-processing of the MEG/EEG recordings:<<BR>>use your constructor's software, or other software solutions (MNE, EEGLab, etc.). [[Links|See here]]. * MRI segmentation:<<BR>>use !FreeSurfer, !BrainSuite or !BrainVisa. [[Links|See here]]. == Requirements == !BrainStorm is written in Matlab code only, thus it can run on any operating system supported by Matlab (including Windows, Linux, MacOS...). If you have a Matlab licence: * You can download and run directly the !BrainStorm source scripts, * Minimum Matlab version: 7.1 (= R14-SP3) If you do not have a Matlab licence: * You can download the !BrainStorm binaries corresponding to your operating system. * The executables are build using the Matlab Compiler (mcc) * They will install automatically the Matlab Component Runtime (MCR) on your computer, a freely redistributable library |

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 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 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 31,000 accounts. See our 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 online tutorials and support through our forum but there is nothing better than a course to make your learning curve steeper. Consult our training pages for upcoming opportunities to learn better and faster.
Finally, have a look regularly at our 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.
