Development of the noradrenergic innervation of neocortex
Brain Research, 1979The development of the noradrenaline (NA)-neuron innervation of rat neocortex was studied by fluorescence histochemistry, high affinity uptake of [3H-]NA, and biochemical assay of regional NA content. Fluorescence histochemistry indicates that NA axons enter areas of developing neocortex prenatally and the innervation matures rapidly during early ...

Anxiety Disorders: Noradrenergic Neurotransmission
2005The past decade has seen a rapid progression in our knowledge of the neurobiological basis of fear and anxiety. Specific neurochemical and neuropeptide systems have been demonstrated to play important roles in the behaviors associated with fear and anxiety-producing stimuli.

The effect of clorgyline on noradrenergic function
Psychopharmacology, 1985A low dosage of the specific MAO-A inhibitor clorgyline (5-10 mg/day) was administered chronically to 10 depressed patients. Peripheral noradrenergic activity, as assessed by measurements of the plasma norepinephrine (NE) concentration, heart rate, and blood pressure, was determined before and after drug treatment. The administration of a low dosage of

A modulator of some noradrenergic processes
Naturwissenschaften, 1977of entrainment of these biological periodicities. Within the range of entrainment the phase relationship between the rhythms of photoperiod and those of testis size and molt changes systematically as a function of the period of the former: as the period of the photoperiodic cycle decreases, the phase of the testicular rhythm (e.g., testicular maximum ...

Noradrenergic Mechanisms in Ethanol Diuresis
Alcoholism: Clinical and Experimental Research, 1986Neurotransmitter mechanisms that mediate the effect of ethanol on urine output were examined in male rats. To establish the neuronal systems involved in the diuretic action of ethanol, urine output was evaluated in animals pretreated with various pharmacological agents.

Effects of mianserin on noradrenergic mechanisms
Journal of Psychiatric Research, 1984Mianserin increased stimulation-induced release of noradrenaline from guinea-pig atria and brain cortex slices. The increase still occurred when neuronal reuptake of noradrenaline was blocked by cocaine. Mianserin blocked the neuronal uptake of 3H-noradrenaline only in high concentrations (1 microM in atria produced 40% block; 10 microM in cortex ...

Noradrenergic and dopaminergic interrelation in schizophrenia
Psychiatry Research, 1994Growth hormone (GH) and prolactin (PRL) responses to the acute administration of clonidine (150 micrograms) and apomorphine (0.5 mg) were investigated in parallel in 20 drug-free subchronic and chronic schizophrenic patients and in nine control subjects.

Adrenerge und noradrenerge Systeme
2012Dieses Kapitel gibt einen kurzen Uberblick uber die Verteilung adrenerger und noradrenerger Zellen und ihre wichtigsten Funktionen. Als Angriffspunkte fur Arzneimittel oder Gifte dienen synthetisierende und abbauende Enzyme, Transportproteine in der Plasma- bzw. Vesikelmembran sowie pra- und postsynaptische Rezeptoren fur Adrenalin und Noradrenalin.

Noradrenergic Nervous Activity in Migraine
Archives of Neurology, 1984The autonomic nervous function in patients with migraine was studied during headache-free intervals. The following observations were made: (1) a decrease in overshoot in Valsalva's maneuver; (2) orthostatic hypotension; (3) low levels of plasma norepinephrine in the steady state; (4) failure in elevation of the plasma norepinephrine level after head-up

Noradrenergic Modulation of Excitotoxicity
1992The noradrenergic system originating in neurons of the locus coeruleus diffusely innervates forebrain structures. It is thought to modulate synaptic activity in many ways; noradrenaline has presynaptic actions on auto- and heteroreceptors and post-synaptic actions on several classes of receptor that influence second messenger systems and ionic ...
