Abstract

Medial hypothalamic sites previously shown to elicit either flight or defense were stimulated in the anesthetized cat. The rate of blood flow from the adrenolumbar (AL) vein ipsilateral to the side of stimulation was measured, as well as the adrenal output of norepinephrine and epinephrine (E). Stimulation at nearly 15% of the hypothalamic sites increased ipsilateral AL venous flow more than 20% over baseline rates. These sites also significantly increased heart rate, mean arterial pressure, and output of E from the ipsilateral adrenal gland. These observations suggest that hypothalamic sites where stimulation increased AL venous flow may overlap with regions that selectively mediate the release of E from the adrenal medulla.
