For an overview of the extensive functionality of BESA Research, it is best to take a look at our tutorials.Tutorials 1-7 below have been recently revised for BESA Research 5.3. An application of the new MATLAB interface is shown in Tutorial 3. The new CLARA 3D imaging technique is part of Tutorial 4.
The following tutorials can be downloaded:
- Tutorial 1: Introduction to discrete source analysis (7 Jan 2010). Introduction to the basics of source analysis and the BESA Research user interface using simulated EEG data.
- Tutorial 2: EEG-fMRI Coregistration, preprocessing, ERP & source analysis (7 Jan 2010). All steps of data analysis from preprocessing to artifact rejection, averaging, source analysis and integration of fMRI.
- Tutorial 3: Batch Scripts, multiple subjects & conditions, MATLAB interface (7 Jan 2010). Using batch scripts to generate a grand average source model and to obtain robust individual source waveforms in group studies. Using the MATLAB interface for cross-subject statistical analysis.
- Tutorial 4: Distributed source imaging (7 Jan 2010). Introduction the new 3D volume imaging techniques in BESA Research including the new CLARA method. Includes a discussion of the effects of regularization.
- Tutorial 5: Artifact correction (22 Feb 2010). Artifact correction in continuous and averaged data. Demonstration of source analysis in the presence of artifacts.
- Tutorial 6: Time-frequency analysis and Source coherence (22 Feb 2010). Introduction to the concept of source montages and time-frequency analysis with application to a simulated and a real example of error-related negativity data.
- Tutorial 7: Multiple source beamformer (22 Feb 2010). Demonstration of the BESA Multiple Source Beamformer to image oscillatory activity. Hands on simulated and real data.
