The coherence between the stimulation signal and the EEG has been used in the detection of evoked responses, However, the detectors performance depends on both the signal-to-noise ratio of the responses and the number of data segments used in the coherence estimation, Recently, the multiple coherence between the stimulation signal and the EEG has been suggested as a way of improving such detection, In this work such methodology is farther investigated using Monte Carlo simulations, and the effectiveness of the method is illustrated on data recorded from 12 young normal subjects daring rhythmic photic simulation.
