title: The hypotensive effect of centrally administered tyrosine.
abstract: Intraventricular injection of 15 microgram L-tyrosine results in a significant reduction in blood pressure in the spontaneously hypertensive rat. An increase in the turnover of norepinephrine as indexed by MOPEG-SO4 is observed concurrently. The data are consistent with the previously suggested depressor role of certain central noradrenergic neurons.
