In unanesthetized, free moving cats the amplitude of round window N-sub(1) neural responses to clicks was correlated with the EEG, the cervical EMG, the electronystagmogram, and the animal's behavior. The results showed that the main differences in the responses to clicks between desynchronized and synchronized sleep and between sleep and wakefulness are caused by changes in the activity of the middle ear muscles. In particular the striking phasic reduction of N-sub(1) during desynchronized sleep is produced by twitches of the intra-aural muscles. (41 ref.) ((c) 1997 APA/PsycINFO, all rights reserved)

Abstract
In unanesthetized, free moving cats the amplitude of round window N-sub(1) neural responses to clicks was correlated with the EEG, the cervical EMG, the electronystagmogram, and the animal's behavior. The results showed that the main differences in the responses to clicks between desynchronized and synchronized sleep and between sleep and wakefulness are caused by changes in the activity of the middle ear muscles. In particular the striking phasic reduction of N-sub(1) during desynchronized sleep is produced by twitches of the intra-aural muscles. (41 ref.) ((c) 1997 APA/PsycINFO, all rights reserved)
