Introduction

BrainStorm is an integrated free Matlab toolkit 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.

BrainStorm features include:?BrainStorm/brainstorm/TutorialImportCTFData.html

• ?Translation routines to get the user data into the BrainStorm database - Import filters include translators ofCTF Systems Inc., and soon, Neuromag and BTi data formats (contributions are welcome);

• ?Data visualization tools: Various time series displays; Data mapping on the head surface; Generate slides and animations; Channel selection; Data filtering, 3D Surface rendering

• ?MRI visualization and co-registration: Import MRI scans, co-registration with the MEG/EEG coordinate system; Superimpose MEG/EEG sources and f-MRI analyze results to the MRI ; Volume rendering; Scalp segmentation

• ?Forward modeling includes the single sphere and the overlapping sphere approaches ; realistic head models using BEM and FEM (new)

• ?Inverse modeling features the RAP-MUSIC approach using current dipole models but also 1st-order multipole models of the primary neural current sources. Models for synchronous pairs of sources are also

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
