[Dynamics of sleep and the waking state after labyrinthine deafferentation].
The author carried out studies on Awake state and sleep (slow and paradoxal) after lybyrinth deafferentation. The states were evaluated by behavior, EEG, myogram and eye movements. The labyrinth defferentation was performed in combination (chemical and mechanical). Bilateral labyrinth deafferentation reduced the duration of the awake state from 30% to 17%, p less than 0.001. The slow sleep was increased at the same time but there was no statistical significance. The parodoxal sleep was due both to the increased number of episodes of parodoxal sleep and to the increased of their mean duration. The latent period of the first appearance of the episode of paradoxay sleep was shortened.
