</span></div>This simulation, made by Zeynep Akalin Acar at the Swartz Center for Computational Neuroscience (SCCN), UCSD, shows (on the left) 30 cm-scale cortical EEG source areas, animated by EEG source waveforms decomposed from actual EEG data using independent component analysis (ICA) in EEGLAB. The speed of the animation is one fifth real time; the color scale is (red +, blue -, green 0). The image on the right shows the summed projections of the 30 sources to the scalp -- the EEG field produced by these sources. The simulated EEG animation was computed in the <a href="http://sccn.ucsd.edu/nft">NFT</a> toolbox using an accurate boundary element method (BEM) electrical head model based on a volunteer subject magnetic resonance (MR) head image. The animation illustrates the very broad point spread from small source areas of locally synchronous field activity (cortical EEG sources) to the scalp, and the character of the EEG data moving field pattern.</span><br clear="all">
