Results from this study3

No result from this study comes from a test of the peptide.

Natural levels measured3

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Mechanism

    In the rabbit brain, immunofluorescence detected some cell bodies that contain the body's own DSIP in the diagonal band of Broca and the anterior part of the hypothalamus.

    In plain wordsIn rabbits, the body's own DSIP was found in some nerve cell bodies in the diagonal band of Broca and front hypothalamus.

    Summary · context
    Using the indirect immunofluorescence method, the distribution of the Delta Sleep Inducing Peptide (DSIP)-containing neurons was studied in the rabbit brain.

    This result measures the body's own Delta sleep-inducing peptide (DSIP). Nobody was given the peptide. It is not evidence about taking it.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Mechanism

    In the rabbit brain, large populations of fibers and terminals that contain the body's own DSIP were seen mainly in the organum vasculosum of the lamina terminalis, preoptic areas, subfornical organ, thalamus, ventromedial hypothalamus and infundibulum.

    In plain wordsIn rabbits, the body's own DSIP was found in many nerve fibers and endings in several brain areas, such as the thalamus and hypothalamus.
