title: Effect of chronic intracerebroventricular infusion of cholecystokinin on respiration and sleep.
abstract: We investigated the effect of chronic intracerebroventricular infusion of the sulfated cholecystokinin octapeptide (CCK-8S) on sleep pattern and respiratory rate. The results indicate a depression of respiratory rate during Non-REM and REM sleep as well as an increase in the number of REM periods occurring per hour of Non-REM sleep. It is suggested that central release of CCK-8S is capable of modulating the automatic regulation of respiration during sleep and altering the normal sleep-waking pattern.
