BESA RESEARCH is the most widely used software for source analysis and dipole localisation in EEG and MEG research. It is a highly versatile and user-friendly Windows® program with optimised tools and scripts to preprocess raw or averaged data for source analysis.
BESA Research provides fast and easy hypothesis testing, a variety of source analysis algorithms, integration with MRI and fMRI, standardised realistic head models (FEM) as well as the possibility to import individual head models (FEM) generated by BESA MRI 2.0.
Beyond dipole source localisation
BESA Research covers the whole range of signal processing and analysis from the acquired raw data to dynamic source images:
- Data review and processing
- Source montages and 3D whole-head mapping
- ERP analysis and averaging
- Source localisation and source imaging
- Cortical mapping and visualisation in standard MRI
- Individual MRI and fMRI integration with BESA MRI and BrainVoyager
- Source coherence and time-frequency analysis
Source coherence for enhanced viewing of brain activity
BESA Research transforms the surface signals into brain activity using source montages derived from multiple source models. This allows the researcher to display ongoing EEG/MEG, single epochs, and averages with much higher spatial resolution.
The Source Coherence Module provides an extremely fast and user-friendly implementation of time-frequency analysis based on complex demodulation. Users can create event-related time-frequency displays of power, amplitude, or event-related (de)synchronisation and coherence for the current montage using brain sources or surface channels. Induced and evoked activities can be separated. Source coherence analysis reveals the functional connectivity between brain regions by reducing the volume conduction effects seen in surface coherence.
