The effect of cervical lymph node extirpation on the amount of sleep was studied in rabbits with chronically implanted electrodes. Cervical lymphatic blockage resulted in a selective and significant increase in the amount of deep slow wave sleep between the 6th and 10th days after surgery. The transient changes observed on the first days were attributed to the prolonged effect of anaesthesia. The results support the hypothesis that the functional alterations are brought about by a transient decrease in the tonic activity of the ascending reticular activating system.
