abstract：:Patients receiving opioids report feeling sleepy, but opioids actually inhibit the rapid eye movement phase of sleep (REM). Inhibition of REM sleep is followed by a rebound increase in REM sleep associated with cardiopulmonary complications. The medial pontine reticular formation (mPRF) is a brain region from which mo...
