Task-dependent signal variations in EEG error-related potentials for brain-computer interfaces.

abstract：OBJECTIVE:Most recent steady-state visual evoked potential (SSVEP)-based brain-computer interface (BCI) systems have used a single frequency for each target, so that a large number of targets require a large number of stimulus frequencies and therefore a wider frequency band. However, human beings show good SSVEP respo...
