Characteristics of hypotension elicited by electrical stimulation of the lateralhypothalamusin anaesthetized dogs.
Electrical stimulation of the lateral hypothalamus near the paraventricular nucleus hypothalami, resulted in : hypotension, light bradycardia, decrease of the left ventricular systolic pressure without increase of the left ventricular  end-diastolic pressure or left ventricular output, femoral vasodilatation and occasionally renal vasodilatation. The hypotensive reactions were potentiated by baroreceptor deafferentation. They were not blocked by anticholinergic, antihistaminic or antidopaminergic agents.
