BESA has a highly interactive and easy-to-use window for source
analysis. All relevant information is available at one glance including
data, PCA, source waveforms and source localization in 3D head schemes
or standardized MRI. You can choose among a variety of state-of-the-art
source modeling techniques and head models. 2D and 3D source imaging can
be performed with projection onto a standardized MRI.
Source Localization
- Highly interactive graphical user interface for fast hypothesis
testing
- Spatio-temporal multiple dipole and regional source modeling
- Automated source fitting: RAP-MUSIC, Genetic algorithm
- Minimum norm images based on the individual brain surface
- Realistic standardized FEM and multi-shell ellipsoidal head
models
- PCA analysis with generation of spatial source components
Source imaging
- 3D imaging of oscillatory activity using the multiple source
beamformer (MSBF)
- Source projection onto standardized or individual MRI
- 3D mapping of source activity onto scalp and cortical
surface
- 3D movie of maps and dipoles using source waveforms
- Tomographic source sensitivity display
- Automated multiple source probe scans (MSPS) for model
validation
Source import and export
- Direct transfer of source models between subjects and
conditions
- Export of source models and source waveforms in ASCII
- Creation of source montages
- Coordinate systems: Talairach / Head / Device / Unit Sphere
- Batch commands for many source analysis functions
