Acute control experiments were performed on decerebrate cats or on cats under nembutal anesthesia (NA), in both cases after curarization. Results were: In cats with chronically implanted electrodes, the neural cochlear responses are increased during attentive wakefulness compared to those observed during synchronized sleep and relaxed wakefulness. This increase can still be observed after cutting the crossed and uncrossed fibers of the olivo-cachlear bundle. In cats under NA, neither stimulation of the cervical sympathetic trunk, nor stimulation of the sympathetic center in the brain stem exerts any influence upon the round window response. (22 ref.)

Abstract
Acute control experiments were performed on decerebrate cats or on cats under nembutal anesthesia (NA), in both cases after curarization. Results were: In cats with chronically implanted electrodes, the neural cochlear responses are increased during attentive wakefulness compared to those observed during synchronized sleep and relaxed wakefulness. This increase can still be observed after cutting the crossed and uncrossed fibers of the olivo-cachlear bundle. In cats under NA, neither stimulation of the cervical sympathetic trunk, nor stimulation of the sympathetic center in the brain stem exerts any influence upon the round window response. (22 ref.)
