Journal of Chemical Neuroanatomy, 2000
The author outlines the history of the locus coeruleus from its discovery to the latest research findings. Although Russel's report in Texas has been believed to be the first break-through scientific article of this neuronal structure, there were two preceding, anatomical and physiological, studies made by Japanese groups.

Response of the locus coeruleus to asphyxia
Bulletin of Experimental Biology and Medicine, 1977To ascertain the mechanisms of the locus coeruleus (LC) function the response of the locus coeruleus neurons to the experimental sharp asphyxia was investigated by the light and electron microscope techniques. Apart from the specific nervous effect (directly through the LC axons and through the stem reticular formation), LC produced humoral influence ...

Release of neurotransmitters in the locus coeruleus
Progress in Neurobiology, 1998In the past 15 years the release of neurotransmitters and their metabolites in the locus coeruleus (LC) has been studied by using three approaches: microdialysis; push-pull superfusion; and voltammetry. These sophisticated techniques, which render it possible to follow the time course and magnitude of neurochemical changes in anaesthetized and ...

The human locus coeruleus and anxiogenesis
Brain Research, 1994Electrical stimulation of locus coeruleus (LC), via permanently implanted electrodes with confirmed localization and effectiveness, did not elicit any subjective or behavioral manifestations of anxiety. This is evidence against the hypothesis that LC is a mediator of anxiogenesis in man.

Opioid Inhibition in Locus Coeruleus
Journal of Neurophysiology, 19951. Inhibition of locus coeruleus (LC) neurons by opioids is mediated by hyperpolarization associated with an increase in potassium conductance. However, opioids caused an outward current even at potentials more negative than the potassium equilibrium potential in the majority of LC neurons recorded in brain slices cut in the horizontal plane. 2.

Locus Coeruleus Function in Enuresis
Scandinavian Journal of Urology and Nephrology, 1999There are four neuronal networks projecting to many areas of the brain. All networks relate closely to arousal and sleep function. Among the four networks, the noradrenaline projection network, originating from the locus coeruleus (LC), is the system most typically responsible for arousal. This study shows that the LC is activated by the stimulation of

European Journal of Pharmacology, 2002 The interaction between the locus coeruleus and dorsal raphe nucleus was investigated by means of dual-probe microdialysis in conscious rats. The release of noradrenaline and 5-hydroxytryptamine (5-HT) after inhibition or stimulation of locus cocruleus ...

Labyrinthine Influences on Locus Coeruleus Neurons
Acta Oto-Laryngologica, 1988The locus coeruleus (LC) complex, located in the dorsolateral pontine tegmentum, is composed principally of noradrenergic neurons, which project to broad regions of the CNS, including the spinal cord. Experiments were performed in precollicular decerebrate cats to ascertain whether units histologically identified within the LC complex, and having the ...

Angiotensin II and the locus coeruleus
1991The locus coeruleus (LC) is a putative site of action for angiotensin II in the brain. Immunocytochemical studies have identified angiotensin II-like immunoreactive material in nerve terminals innervating the LC, and the LC contains one of the highest densities of angiotensin II receptor binding sites in the rat brain.

The locus coeruleus, norepinephrine, and memory in newborns
Brain Research Bulletin, 1994Use of learned odor cues by newborn rats is critical for pup survival. Rat pups acquire approach responses to maternal odors through an associative conditioning mechanism. This learned behavioral response is accompanied by a modification of olfactory bulb neural response patterns to the learned odor.
