BESA Simulator

BESA Simulator

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
