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 available. Minimum-norm imaging of the cortical current density is featured, with co-registration to the anatomy.

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
