DipoleSimulator

DipoleSimulator is a free educational tool developed by Patrick Berg designed to simulate EEG or MEG activity generated by model sources. The latest version of the program, 3.3.0.2, offers extensive features to facilitate a deeper understanding of dipole modeling and its relationship with surface EEG and MEG data.

Users can download the program, which is only 1.7 MB in size, and supports a variety of Windows operating systems including Windows XP, 7, 10, and 11. The program caters to the Education category, specifically the Science Tools subcategory. Other versions like 3.3 are also available, though 3.3.0.2 remains the latest.

DipoleSimulator allows users to simulate both EEG and MEG, view maps resulting from a dipole within the head, add up to 20 dipoles, and generate independent waveforms of each dipole. The program provides flexibility in referencing methods, including reference-free, average reference, Laplacian (CSD) reference, or using any electrode/sensor as reference. Users can also define linked electrode pairs as references.

Among its various functionalities, DipoleSimulator lets users place a cursor anywhere in the time interval to view maps of data at specific points, specify parameters for the spherical head model, and add coherent noise to the data in terms of RMS level and alpha activity level. The program also includes educational features, allowing users to learn about filters by displaying the effects of various filters on simulated data. More
