Functional separation of adrenergic and cholinergic fibers to skeletal muscle vessels

open access: yesAmerican Journal of Physiology, 1965
The hypothesis that sympathetic innervation to skeletal muscle vasculature contains functionally distinct adrenergic and cholinergic fibers was investigated utilizing the dog isolated perfused gracilis muscle. The use of hemicholinium in an attempt to abolish cholinergic dilatation, but not adrenergic constriction, in response to intermittent nerve ...

Cholinergic neurons in the rat hippocampus do not compensate for the loss of septohippocampal cholinergic fibers

Neuroscience Letters, 1988
In recent studies a small number of choline acetyltransferase (ChAT)-immunoreactive, supposedly cholinergic, neurons intrinsic to the rat hippocampus have been described. Here we report that these neurons are not capable of sprouting in response to removal of the cholinergic input to the hippocampus from the medial septum/diagonal band complex.

Cholinergic and GABAergic fibers in the stria medullaris of the rabbit

Brain Research Bulletin, 1977
Abstract After placing uni- and bilateral electrolytic lesions in the habenula (Hb), stria medullaris (SM), septum (Sep) and lateral preoptic area (LPA), activities of choline acetyltransferase (ChAc), acetylcholinesterase (AChE) and L-glutamic acid decarboxylase (GAD), which are the synthesizing and degradating enzymes of acetylcholine and the ...

Cholinergic through-fibers in the rat superior cervical ganglion

Journal of the Autonomic Nervous System, 1981
In questo lavoro, nell'ambito della descrizione delle connessioni tra fibre pregangliari e neuroni principali gangliari, è stata messa in evidenza la presenza di un contingente di fibre pregangliari che attraversano senza interrompersi il ganglio cervicale superiore di ratto, proiettando nei tronchi postgangliari.

Cortical cholinergic fibers in aging and Alzheimer's disease: A morphometric study

Neuroscience, 1989
A histochemical method for acetylcholinesterase was used to assess the regional density of acetylcholinesterase-rich (putatively cholinergic) axons in the cerebral cortex. A dense plexus of these fibers was observed in all cortical areas. The entorhinal, cingulate and inferotemporal regions were used for quantitative analysis.

Nerve growth factor promotes collateral sprouting of cholinergic fibers in the septohippocampal cholinergic system of aged rats with fimbria transection

Brain Research, 1992
Nerve growth factor (NGF) was injected intraventricularly into aged (24 months) rats with unilateral fimbria transection. Controls received intraventricular injections of cytochrome c. A quantitative analysis of acetylcholinesterase (AChE)-positive fibers was used to evaluate whether the NGF treatment can stimulate regeneration and reinnervation of the
