A negative component of event-related brain potentials which is specific to stimulus change (Näätänen and Gaillard 1983; Näätänen 1986), the “mismatch negativity” (MMN), seems to reflect an automatic comparing process. This comparison is thought to be between the neural representation of standard stimuli — the “neuronal model of the stimulus” (Sokolov 1960) — and the neuronal pattern elicited by deviant stimuli. Although electrical scalp recordings (Simson et al. 1977) and magnetoencephalographic data (Elberling et al. 1980, 1982; Hari et al. 1982, 1984) suggest that the generators underlying the MMN involve several mechanisms in the auditory cortex, they give no information about other possible mechanisms on which the MMN may depend.
