DipoleSimulator 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 the program you can perform the following operations:
- Simulate both EEG and MEG
- See maps resulting from a dipole anywhere within the head
- Add up to 20 dipoles to a model
- Generate independent waveforms of each dipole (source waveform)
- 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 view maps of the data 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
- Save and read the models you have generated. Read BESA par and bsa models
- Save the generated data in BESA avr (ASCII) format
- If the program file, DipoleSimulator.exe, is located in the BESA Research root folder, DipoleSimulator can use the standard FEM models that come with BESA Research 6.0

Place dipoles into the brain, create source waveforms and observe the propagation and overlap in scalp maps and waveforms.
