Abstract :
The electrical activity in event-related brain potentials (ERP) generated by spatially, but not necessary temporary, common sources in two different experimental conditions, can effectively be suppressed with a generalized singular value decomposition (GSVD) of the elicited ERPs in favour of the activity of the source configurations that are specific to either of the two experimental conditions
