  • Title: Cerebrospinal fluid production by the choroid plexus and brain.
    Author: Milhorat TH, Hammock MK, Fenstermacher JD, Levin VA.
    Journal: Science; 1971 Jul 23; 173(3994):330-2. PubMed ID: 4997797.
    Abstract:
    The production of cerebrospinal fluid and the transport of (24)Na from the blood to the cerebrospinal fluid were studied simultaneously in normal and choroid plexectomized rhesus monkeys. Choroid plexectomy reduced the production of cerebrospinal fluid by an average of 33 to 40 percent and the rate of appearance of (24)Na in the cerebrospinal fluid and its final concentration were proportionately reduced. In both normal and plexectomized animals, (24)Na levels were found to be markedly greater in the gray matter surrounding the ventricles and in the gray matter bordering the subarachnoid space. That sodium exchanges in these two general areas of the brain may be linked to the formation of the cerebrospinal fluid is discussed here.
