BESA Simulator is a free program written by Patrick Berg for the simulation of EEG or MEG activity generated by model sources. The purpose of this tool is to provide a better understanding of dipole modeling and the link of brain sources with surface EEG and MEG data.
With BESA Simulator you can:
- Simulate both EEG and MEG data
- See maps resulting from a dipole anywhere within the head
- Add any number of dipoles to a model
- Generate independent waveforms of each dipole (source waveform). You can also read in source waveforms from an ASCII file (BESA swf)
- See the surface data resulting from the model, as reference-free, average reference, Laplacian (CSD) reference, or using any electrode/sensor as reference. Linked electrode pairs can also be defined as reference
- Place a cursor anywhere in the time interval and visualize the scalp activity at that time point
- Specify the parameters of the spherical head model
- Add coherent noise to the data defined in terms of rms level and level of alpha activity
- Learn about filters by displaying the effects of applying various types of filter to your simulated data
- Use any electrode or MEG sensor configuration. MEG configurations from 4-D, CTF, and Neuromag systems are supplied as examples.
- Save and read the models you have generated. In addition to the internal model format (*.mod). read BESA bsa and par models.
- Save the generated data in BESA avr (ASCII) format
- Simulated raw data can be saved in BESA Simple Binary (Generic) format.
- Simulate activity using individual head models (FEM) generated by BESA MRI
