title: Preferential hindquarter vasodilation in the hypotension induced by GABA injection into the cisterna magna of conscious rats.
abstract: Injection of GABA into the cisterna magna of conscious rats induced a vasodilation in the hindquarter without significant change in the renal and superior mesenteric areas, when arterial pressure and heart rate markedly decreased. This circulatory change indicates that GABA decreased arterial pressure as an effect on the CNS, in particular, through a hindquarter resistance reduction, along with a bradycardia.
