## Abstract In the sheep, the pineal hormone melatonin displays nocturnal levels 20 times as high in the cerebrospinal fluid of the third ventricle as in the jugular blood. Moreover, in the pineal recess, the evagination of the third ventricle into the pineal stalk, the levels of melatonin in the c
