Selective Activation of Noradrenaline and Adrenaline Producing Cells in the Cat's Adrenal Gland by Hypothalamic Stimulation

Abstract
By stimulating different parts of the hypothalamus in the cat, it has been possible to show that adrenal medullary secretion often contains preferentially adrenaline or noradrenaline. The results indicate that the two horomones are secreted from different cells with separate innervation.
