We have recorded simultaneously the auditory responses of neurons in the auditory and perirhinal cortices. While the former, a low order sensory region, showed similar response magnitudes across vigilance states, the higher order area showed robust attenuations in both NREM and REM sleep. Furthermore, the latency of neurons has been found to predict the response attenuation.
