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.

    In human brain tissue, very few oxytocin fibres were present in the amygdala and hippocampus.

    In plain wordsIn human brain tissue, only very few fibres containing the body's own oxytocin were found in the amygdala and hippocampus.

    Summary
    Very few VP and OXT fibers were present in the amygdala and in the hippocampus, mainly around the rostral tip of the lateral ventricle on the level of the pes hippocampi.

    Summary · context
    In the present study, the distribution of extrahypothalamic vasopressin (VP) and oxytocin (OXT) in the human brain was investigated by means of immunocytochemistry.

    This result measures the body's own Oxytocin. Nobody was given the peptide. It is not evidence about taking it.

  2. 02HumanEndogenous levelObservational studyOther

    In human brain tissue, the locus coeruleus contained oxytocin fibres, to a lesser extent than vasopressin fibres.

    In plain wordsIn human brain tissue, the locus coeruleus had fibres with the body's own oxytocin, fewer than vasopressin fibres.

    Summary
    The locus coeruleus (LC) contained dense networks of VP fibers and, although to a lesser extent, OXT fibers over its entire rostrocaudal extension.
