title: The phases of sleep and wakefulness after bilateral labyrinth destruction in chronic cats.
abstract: After bilateral destruction of the labyrinths, the duration of paradoxical sleep increased from 4% in the intact animals to 8% after destruction. This increase was the result of an increase from 2.2 to 2.6 in the average number of epiodes of paradoxical sleep as well as of an increase from 3.2 to 5.5 min of the duration of each episode of paradoxical sleep. One latency of the first appearance of an episode was shortened, from the 77th min at the beginning of registration to the 43rd min after destruction. During this time the duration of wakefulness decreased from 30% to 17%.
