N2 - Evoked potential threshold estimation can be made truly objective by using statistically based methods. In general, time domain analysis is preferable for responses which are impulsive (temporally narrow, spectrally broad), whereas frequency-domain analysis is more appropriate for tonal responses (spectrally narrow, temporally broad). In both time and frequency domains, methods comparing evoked potential power to noise models are robust and powerful. For spectrally narrow responses such as steadystate evoked potentials, the performance of magnitudesquared coherence, the ratio of grand average power to mean subaverage power, is superior to that of other methods for objective response detection.
