Dipole Simulator

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
