EEGLAB is a MATLAB toolbox distributed under the free BSD license for processing data from electroencephalography (EEG), magnetoencephalography (MEG), and other electrophysiological signals.
Alternatively, ICA components representing brain activity may be further processed and analyzed.
EEGLAB also allows users to group data from several subjects, and to cluster their independent components.
[4][5] In 1997, a set of data processing functions was first released on the Internet by Scott Makeig in the Computational Neurobiology Laboratory directed by Terry Sejnowski at the Salk Institute, under the name “the ICA/EEG toolbox”.
In 2003, Delorme and Makeig joined efforts to release the first stable and fully documented version of EEGLAB.
