[Development of slow wave sleep after lesion of the anterior Raphe nuclei of the newborn rat].
Sub-total lesions of the Nucleus Raphe Dorsalis and Centralis Superior have been performed on 4 to 10 day-old puppy rats. The sleep cycles of these animals, studied up to one month of age, were modified neither quantitatively nor qualitatively by the lesions. Slow sleep with cortical synchronisation was normally present at 21 days of age. It is concluded that the sleep of such animals might be under the control of another system than the serotoninergic Raphe nuclei.
