Overview


 

Find the Product That Fits Your Needs

BESA offers four different products which cover many usage scenarios in neurophysiological data analysis in EEG and MEG.

Data Formats

Manage EEG / MEG data recorded by different systems in one application:
BESA Research can read files of more than 40 different EEG / MEG data formats. Exporting whole files or segments to EDF is possible.

ERP/ERF

Use BESA Research for complete pre-processing and analysis. It includes artifact correction and rejection, peak finding, paradigm definition and grand averaging.
Use BESA Statistics to perform group and /or condition comparisons; it intrinsically solves the multiple testing problem and runs parameter free statistics. F-Test and t-Test are available.

EP

Use BESA Research to perform artifact rejection, averaging, and analysis. Save time with the intuitive, graphical user interface.

Source Analysis/Source Imaging

BESA Research is the most comprehensive toolbox for EEG / MEG source localization. Pattern search and averaging support your discrete and distributed source analysis. Generate source montages for reviewing the data. Fit single dipoles and regional sources, or use volume or cortical imaging methods for distributed source imaging. If you have no MRI data available, simply choose realistic children’s and adults’ FEM head models.

BESA MRI is required for source analysis with individual MRI. The integrated workflow concept makes it very easy to use. Create a 4-layer individual head model and co-register with EEG / MEG sensors.

Brain Connectivity and Spectral Analysis

Use BESA Research to calculate DSA or FFT of your data. Time frequency transforms, coherence and source coherence methods are available in the included Source Coherence module and in the BESA Connectivity module.

Cross-subject Statistics

Perform cluster permutation statistics on ERPs, source waveforms, images, time-frequency and coherence results with BESA Statistics.

Spikes in Epilepsy

(research use only outside the EU)
Use BESA Research to mark spikes manually. 3D Mapping and source montages support evaluation of the interictal activity. Run a pattern search to find similar patterns quickly and reliably. Average spikes for discrete or distributed source analysis. Analyze spike onset and check for propagation. If you have MRI data available, use BESA MRI to create an individual head model for source analysis.

Seizures in Epilepsy

(research use only outside the EU)
Use BESA Research to visualize seizure epochs in DSA. FFT supports your seizure analysis. Localize seizure onset using phase maps and averaged cycles. If you have MRI data available, use BESA MRI to create an individual head model for source analysis.

Clinical MEG

(research MEG data analysis only outside the EU)
Use MEG source montages in BESA Research to save time and facilitate MEG data review. Search for spikes and perform source analysis in MEG.
