Noradrenergic fiber sprouting in the cerebellum
Brain Research Bulletin, 1982Abstract In order to attain a better understanding of the sprouting response of noradrenergic fibers in the central nervous system (CNS), noradrenergic innervation to the cerebellum was observed by the glyoxylic acid method after a variety of manipulations and in a genetic variant of mouse classified as “Purkinje cell degeneration” (pcd/pcd).

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 ...

Noradrenergic Neurotransmission
2004Publisher Summary Sympathoneural norepinephrine (NE) satisfies the main criteria defining a neurotransmitter: a chemical released from nerve terminals by electrical action potentials that interacts with specific receptors on nearby structures to produce specific physiologic responses. Different stressors can elicit different patterns of sympathoneural

Noradrenergic Challenges in the Affective Disorders
Journal of Clinical Psychopharmacology, 1981The rationale for the use of noradrenergic challenges, i.e., administration of psychopharmacological agents that alter noradrenergic activity, is reviewed in relation to evidence implicating the noradrenergic system as important in the etiology of treatment of the affective disorders.

Possible Noradrenergic Dysfunction in Schizophrenia
Brain Research Bulletin, 1994In spite of extensive studies over the last 2 decades to find direct evidence in support of the dopamine hypothesis of schizophrenia, no undisputed experimental data has been obtained. In contrast, estimation of noradrenalin (another major catecholamine) and its metabolites in postmortem brain and in the cerebrospinal fluid appears to be producing ...

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

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.

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 ...

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 ...
