Results from this study4

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

Natural levels measured4

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)Other

    Social Brandt's voles had higher densities of oxytocin-immunoreactive cells in the medial preoptic area and medial amygdala than solitary greater long-tailed hamsters.

    In plain wordsIn voles, the body's own oxytocin-making cells were denser in two brain areas than in hamsters.

    Summary · context
    Immunoreactive (ir) staining of the neuropeptides oxytocin (OT) and vasopressin (AVP) was performed in the brains of Brandt's voles (Lasiopodomys brandtii) and greater long-tailed hamsters (Tscherskia triton)-two species that differ remarkably in social behaviors.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Other

    Greater long-tailed hamsters had higher densities of oxytocin-immunoreactive cells in the anterior hypothalamus and lateral hypothalamus than Brandt's voles.

    In plain wordsIn hamsters, the body's own oxytocin-making cells were denser in two other brain areas than in voles.

    In both species, females had a higher density of oxytocin-immunoreactive cells in the paraventricular nucleus than males.

    In plain wordsIn both rodent species, females had more of the body's own oxytocin-making cells in one brain area than males.
