Journal ArticleDOI
Tonic vasomotor control by the rostral ventrolateral medulla: effect of electrical or chemical stimulation of the area containing C1 adrenaline neurons on arterial pressure, heart rate, and plasma catecholamines and vasopressin
Christopher A. Ross,David A. Ruggiero,Dong H. Park,Tong H. Joh,Alan F. Sved,Julio Fernandez-Pardal,Julio Fernandez-Pardal,Juan M. Saavedra,Donald J. Reis +8 more
TL;DR: Neurons within the RVL, most probably C1 adrenaline- synthesizing neurons, exert an excitatory influence on sympathetic vasomotor fibers, the adrenal medulla, and the posterior pituitary, as well as under tonic inhibitory control, in part via GABAergic mechanisms.
Journal ArticleDOI
Rostral ventrolateral medulla: selective projections to the thoracic autonomic cell column from the region containing C1 adrenaline neurons.
TL;DR: Anterograde, retrograde, and combined axonal transport methods were used to describe the descending efferent projections of a region of rostral ventrolateral medullary reticular formation important in cardiovascular control.
Journal ArticleDOI
Chemical and structural analysis of the relation between cortical inputs and tyrosine hydroxylase-containing terminals in rat neostriatum
TL;DR: Findings indicate that the cortical and dopaminergic nigral efferents have actions on common recipient neurons in the rat caudate nucleus and provide support for a possible direct axonal interrelationship between these two primary inputs.
Journal ArticleDOI
Direct phosphorylation of brain tyrosine hydroxylase by cyclic AMP-dependent protein kinase: mechanism of enzyme activation.
TL;DR: It is proposed that the pool of native tyrosine hydroxylase is composed of a mixture of enzyme molecules in both active and probably inactive forms, that the active form is phosphorylated, and that phosphorylation produces an active form of the enzyme at the expense of an inactive one.
Journal ArticleDOI
Distribution of neurons containing phenylethanolamine N-methyltransferase in medulla and hypothalamus of rat.
David A. Ruggiero,Christopher A. Ross,Muhammed Anwar,Dong H. Park,Tong H. Joh,Donald J. Reis +5 more
TL;DR: Neurons immunocytochemically labeled with the adrenaline‐synthesizing enzyme phenylethanolamine N‐methyltransferase were mapped in the brain of rat pretreated with colchicine and immunoreactive cells in the C1 and C2 groups were distributed in a more complex manner than described previously.
