(2) Native prolactin can activate the release of dopamine (DA) from mesostriatal nerve terminals, but not from the cell bodies, as estimated by an increase in in vivo DOPAC output from the caudate nucleus and nucleus accumbens and an increase in in vitro DA release from both dorsal and ventral striatum. (3) Prolactin elicits specific behaviors such as yawning, stretching, and extensive grooming when push-pull cannula perfused a defined area within the caudate nucleus. Interesting, no such behaviors were induced when prolactin was infused into the nucleus accumbens. (4) Short-term prolactin does not enhance the in vivo tyrosine hydroxylase activity of mesostriatal nerve terminals. However, prolactin significantly activated tyrosine hydroxylase activity in the tuberoinfundibular DA neurons of the mediobasal hypothalamus.
