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 ?(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 (?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:
  use your constructor's software, or other software solutions (MNE, EEGLab, etc.). ?See here.

• MRI segmentation:
  => use FreeSurfer, BrainSuite or BrainVisa. ?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
