Auditory information processing in sleep: habituation to repetitive stimuli.
Habituation to evoked responses is obvious in waking but still controversial in sleep. Single-response analysis proves short-term habituation of auditory evoked potentials in stage 2 NREM sleep. The data are discussed referring to the two-system hypothesis of sensory processing in sleep and to DC instability and sleep maintenance mechanisms in stage 2 NREM. It is suggested that information processing might continue in sleep.
