Event-related potentials (ERPs) method allows exploring the extent to which the human brain can process auditory information from external world during sleep. ERPs studies demonstrate that information processing is still efficient during sleep, and sometimes in a manner very similar to that observed during wakefulness. They show that the sleeping subject may detect stimulus deviance, as well as the presence of her/his own first name in sequences of equiprobable first names. The hypothesis that some semantic analysis of auditory stimuli remains possible during sleep is confirmed by the persistence of differential ERPs to related or unrelated words during sleep. Furthermore, it seems that linguistic absurdity is accepted in a different manner during paradoxical sleep, since pseudowords (without meaning) yield a similar response to that of related words, while they elicit a more similar response to unrelated words during waking and sleep stage 2.
