ARTIFACT FILTERING
Here is a demonstration of artifact filtering. The aim of this filtering is to cancel signals which do not originate from the brain, while keeping as best as possible those of cerebral origin (See presentation of EEG signal and artifacts).

This filtering has been carried out with the AFOP method (Adaptive Filtering by Optimal Projection) using EEGlab. The matlab program will be available soon on this website.
