Catecholaminergic-to-cholinergic transition of sympathetic nerve fibers is stimulated under healthy but not under inflammatory arthritic conditions

Brain, Behavior, and Immunity, 2015
Objective: Density of sympathetic nerve fibers decreases in inflamed arthritic tissue tested by immunoreactivity towards tyrosine-hydroxylase (TH, catecholaminergic key enzyme).

Orexin fibers in the cholinergic mesopontine tegmentum of the rat

岡山県立大学短期大学部研究紀要, 2002
Orexins, which are recently discovered neuropeptides, are though to play a critical roll in the regulation of sleep-wake state. Neurons producing orexin are preferentially located in the lateral hypothalamus, while orexin fibers are widely distributed in

Synergistic Effect of Serotoninergic and Cholinergic Nerve Fibers

Bulletin of Experimental Biology and Medicine, 2001
The mechanisms of interactions between various compartments of the autonomic nervous system were evaluated by studying sympathetic potentiation of vagal cardioinhibitory action. It was found that this effect is realized through preganglionic serotoninergic nerve fibers making synaptic contacts with intracardiac serotoninergic neurons.

Drinking elicited by cholinergic stimulation of CNS fibers

Physiology & Behavior, 1972
Abstract Carbachol, eserine and atropine were injected into limbic system sites in the brain of the rat. In previous studies, carbachol and eserine were found to elicit the drinking of water at identical loci in limbic system nuclei. Furthermore, atropine injection into one site has been found to inhibit drinking-to-carbachol in another site.

Modulatory effect of imetit, a histamine H3 receptor agonist, on C-fibers, cholinergic fibers and mast cells in rabbit lungs in vitro

European Journal of Pharmacology, 1999
peer reviewedThe pharmacological mechanisms involved in the interactions between C-fibers, cholinergic fibers and mast cells were investigated in tracheally perfused rabbit lungs by measuring the simultaneous release of substance P and histamine in lung ...

The length of hippocampal cholinergic fibers is reduced in the aging brain

Neurobiology of Aging, 2008
Cholinergic deficits occur in the aged hippocampus and they are significant in Alzheimer's disease. Using stereological and biochemical approaches, we characterized the cholinergic septohippocampal pathway in old (24 months) and young adult (3 months) rats.

Reorganization of the septohippocampal cholinergic fiber system in experimental epilepsy

Journal of Comparative Neurology, 2017
AbstractThe septohippocampal cholinergic neurotransmission has long been implicated in seizures, but little is known about the structural features of this projection system in epileptic brain. We evaluated the effects of experimental epilepsy on the areal density of cholinergic terminals (fiber varicosities) in the dentate gyrus.

Occurrence of cholinergic nerve fibers in the human uveoscleral tissue

International Ophthalmology, 1998
We have studied the cholinergic nerve fibers (CNF) of human uveoscleral tissue in normal and pathological conditions (intraocular pressure: (IOP) of various degrees ) and have performed a quantitative image analysis of CNF with the aim of studying an hypothetical association between IOP and the uveoscleral level of cholinergic neurotransmitter in nerve

Distribution of cholinergic and adrenergic nerve fibers in the lacrimal glands of dogs

American Journal of Veterinary Research, 1989
SUMMARY The distribution of postganglionic autonomic nerve fibers in the lacrimal gland and gland of the third eyelid of dogs was studied by use of histochemical techniques. Adrenergic nerve distribution was identified by use of the sucrose-potassium phosphate-glyoxylic acid technique.

Evidence for a cholinergic fiber tract connecting the thalamus with the head of the striatum of the rat

Brain Research, 1977
Placement of electrolytic lesions in the zona incerta or parafascicular nucleus of the rat forebrain resulted in a marked reduction of choline acetyltransferase (ChAc) activity in the head of the striatum 2-4 weeks later. Lesions of the habenula did not cause this effect implying that concomitant destruction of the fasciculus retroflexus with the ...
