[The effect of the intraventricular administration of oxytocin on the functional activity of the epiphysis, adrenals and gonads and on the behavior of rats].

Intraventricular administration of oxytocin (OT) facilitated horizontal locomotion and inhibited their decrease in rats. OT also increased the number of face grooming responses but did not affect the genital grooming. The OT seems to suppress the pineal gland activity, whereas the plasma concentration of testosterone did not change and the corticosterone concentration increased. The OT seems to exert a complex effect on the nervous and endocrine systems.
