BESA Research 7.1 is the most streamlined and comprehensive, user-friendly software for source analysis and dipole localisation in human EEG and MEG research. BESA Research 7.1 is highly versatile, with optimised tools and scripts to preprocess raw or averaged data for source analysis and connectivity analysis.
BESA Research Software
The world's most comprehensive signal processing toolbox for EEG/MEG source localisation
For over two decades, the BESA Research package has set the standard for state-of-the-art EEG and MEG data analysis. Combining an easy-to-use interface with innovative, tailored analysis methods and data review tools, BESA research provides a convenient and extremely smooth pathway for carrying out EEG/MEG data analysis.
BESA Research 7.1 allows fast and easy testing of hypotheses, multiple source analysis algorithms (including cortical imaging and volume imaging methods), integration with MRI and fMRI, and age-appropriate template head models (FEM) along with the option to import individual head models (FEM) generation by BESA MRI 2.1.
The updated software provides many new tools for reviewing and processing your EEG or MEG data. Raw data are directly read using readers implemented for many EEG and MEG file formats, and data processing steps include digital filtering, artefact detection and correction, computation of correlation, and spectral analysis.
BESA Research 7.1 covers the entire process of signal processing and analysis, from the acquired raw data to dynamic source images, allowing data review and processing; source montages and 3D whole-head mapping; ERP analysis and averaging; source localisation and source imaging; cortical mapping and time-frequency analysis; source coherence and time-frequency analysis; source coherence for enhanced viewing of brain activity.
Additional modules compatible with BESA Research are available. Please contact us for information on BESA MRI, BESA Statistics, or BESA Epilepsy.
