Fiber pathways of basal forebrain cholinergic neurons in monkeys
Brain Research, 1987In rhesus monkeys, autoradiographic tracing methods, complemented by immunocytochemical and histochemical techniques, were used to delineate pathways by which cholinergic neurons of the nucleus basalis of Meynert (nbM) and nucleus of the diagonal band of Broca (ndbB) project to forebrain targets.

Reorganization of the septohippocampal cholinergic fiber system in experimental epilepsy
Journal of Comparative Neurology, 2017AbstractThe 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.

Effects of age and sex on the water maze performance and hippocampal cholinergic fibers in rats
Neuroscience Letters, 1999We have examined if age-related deterioration of spatial memory and cholinergic innervation of the dentate gyrus is gender-specific. Aging progressively affected the performance of male and female rats in place discrimination version of the water maze task.

Are there cholinergic through-fibers in the superior cervical ganglion of the mouse?
Histochemistry, 1991Choline acetyltransferase immunocytochemistry was used to detect the presence and distribution of cholinergic through-fibers in the superior cervical ganglion of adult mice. The results revealed a great number of choline acetyltransferase-positive axons in the cervical sympathetic trunk and the varicose terminal axons involved in the innervation of the

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

Occurrence of cholinergic nerve fibers in the human uveoscleral tissue
International Ophthalmology, 1998We 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

Regulation of cerebral cortical blood flow by the basal forebrain cholinergic fibers and aging
Autonomic Neuroscience, 2002This article reviews the study of neural vasodilator mechanisms of the cerebral cortex by basal forebrain cholinergic nerve fibers and their age-related function in rats. During the last decade, we have demonstrated a neural regulatory system of cerebral blood flow in rats involving intracerebral cholinergic vasodilator nerve fibers originating in the ...

Distribution of cholinergic and adrenergic nerve fibers in the lacrimal glands of dogs
American Journal of Veterinary Research, 1989SUMMARY 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.

Properties of Cholinergic Responses in Isolated Parapodial Muscle Fibers ofAplysia
Journal of Neurophysiology, 1999The parapodial neuromuscular junction in the marine snail Aplysia brasiliana is a model synapse for the investigation of neural modulation. The parapodial muscle fibers are innervated by cholinergic motoneurons and by serotonergic modulatory cells.

The cat neostriatum: relative distribution of cholinergic neurons versus serotonergic fibers
Brain and Development, 2000The distribution of choline acetyltransferase (ChAT)-containing neurons and serotonin (5-HT)-containing nerve fibers in the cat neostriatum was investigated by use of immunohistochemical techniques. Both ChAT- and 5-HT-staining techniques were applied to alternate brain sections, thereby allowing a precise comparison of the distribution pattern of ChAT-
