On the use of Laplacian electrodes for Adaptive Brain Interface
In the framework of the construction of a EEG-based brain-computer interface (BCI) some results suggested that EEG patterns can be better detected with EEG data transformed with Surface Laplacian computation (SL) than with the unprocessed raw potentials. Accurate SL estimates require, however, the use of many EEG electrodes, preventing application in a BCI device to be used by laypersons in real-life conditions. The aim of this study was to determine an optimal design for SL electrodes to apply in the portable Adaptive Brain Interface device being developed.
