AbstractBrain-computer interface (BCI) is a new human machine interface. Currently, there is a debate about the genesis of the event-related potentials (ERPs). A constituent of the ERPs, the P300, appears to be closely associated with the cognitive processes of the brain. So this research focuses on the genesis of the P300. The event-related spectral perturbation (ERSP) and the inter-trial coherence (ITC) are used in the time-frequency analysis of the signals. The results shows that at the mean values of ERSP and ITC with a P300 signals are much larger than those without a P300 signals, from which we make a conclusion that two models about ERPs both contribute to the genesis of the P300.
