Brainstorm

Brainstorm is a free Matlab application dedicated to MEG and EEG data visualization, processing and cortical source estimation.
Its rich and intuitive graphic interface does not require any programming knowledge or experience with Matlab.

MEG/EEG visualization and processing:
- Support for most of the common file formats for MEG, EEG and MRI
- Basic pre-processing: frequency filtering, resampling, epoching, baseline removal, averaging, etc.
- Visualization of recordings: time series, 2D/3D topographies
- MRI/EEG/MEG co-registration
- Database and powerful database explorer

Source estimation:
- Forward modeling: spherical models, overlapping spheres, BEM
- Inverse modeling: minimum norm, beamformers
- Visualization of sources: cortex surface, MRI volume

Post-processing:
- Definition of clusters of electrodes
- Regions of interests at cortical level
- Group analysis, registration of individual brains on a template
- Statistical tests: t-test, permutations
