Muscle afferents and activity of respiratory neurons

American Journal of Physiology-Legacy Content, 1961
Respiratory effects of stimulating afferent fibers of muscle, skin and mixed nerve were determined in Nembutal-anesthetized cats. Repetitive stimuli which produced only monosynaptic reflex actions caused augmentation of respiration. When stronger stimuli also activated fibers of a smaller diameter than group I afferents, polysynaptic reflexes were ...

Influence of neck afferents on vestibulospinal neurons

Experimental Brain Research, 1980
The effects of neck afferent stimulation on vestibulospinal neurons in Deiters' nucleus and in the descending nucleus, and the interaction of cervical and vestibular input, were examined extracellularly in decerebrate, decerebellate cats. Many of the vestibulospinal neurons were identified as having axons in the lateral or medial vestibulospinal tract (

The study of airway primary afferent neuron excitability

Current Opinion in Pharmacology, 2002
The activation of airway afferent neurons initiates a variety of reflexes including cough and bronchoconstriction. Like somatic afferent neurons involved in inflammation-induced hyperalgesia, the excitability of airway afferent neurons is not fixed but, rather, can be increased by the action of a variety of mediators produced during inflammation.

Glutamatergic Functions of Primary Afferent Neurons with Special Emphasis on Vagal Afferents

2007
Glutamate has been identified as the main transmitter of primary afferent neurons. This was established based on biochemical, electrophysiological, and immunohistochemical data from studies on glutamatergic receptors and their agonists/antagonists.

Structure-function relationships in identified afferent neurones

Anatomy and Embryology, 1990
The review deals with structure-function relationships in primary afferent and spinal cord neurones that were intracellularly injected with a marker substance (mostly HRP) after physiological identification. At the level of dorsal root ganglion (DRG) cells, there is a significant correlation between soma size and conduction velocity (or diameter) of ...

Nicotinic Acetylcholine Receptors on Vagal Afferent Neurons

Annals of the New York Academy of Sciences, 2001
Abstract: Nicotinic acetylcholine receptors (nAChRs) play an important role in various processes involved in regulating systemic blood pressure. These receptors are expressed at excitatory cholinergic synapses between sympathetic preganglionic neurons and postganglionic sympathetic neurons and link the integrative activities of the CNS with peripheral

Neuropeptides in Primary Afferent Neurons

1990
Traditionally, the primary sensory neurons, having their perikarya in the spinal or cranial sensory ganglia with processes directed towards the periphery and the central nervous system, have been regarded to function as receptive and afferent systems which reflexly activate central effector systems.1 This, however, does not apply to the small diameter ...

5-HT Receptors on Afferent Neurones

1989
Receptors for 5-hydroxytryptamine (5-HT) are widely distributed over the mammalian peripheral nervous system (Wallis, 1981; Fozard, 1984). Those located on afferent neurones generally mediate excitatory actions of 5-HT, with neuronal inhibition being only rarely encountered (Paintal, 1973; Wallis, 1981; Roberts, 1984; Higashi and Nishi, 1982).

Afferent System of Orexin Neurons

2006
A small number of orexin/hypocretin neurons are specifically located in the lateral hypothalamic area (LHA), although these neurons project to almost all parts of the brain except the cerebellum (1,2). Like other neurons in the brain, orexin neurons receive many excitatory or inhibitory inputs, and they output to projection sites by integrating these ...

Afferent Control of Nigral Dopaminergic Neurons

2002
In in vivo extracellular recordings from anesthetized adult rats, midbrain dopaminergic neurons fire spontaneously at low rates, averaging around 4 spikes/second (Bunney et al., 1973; Guyenet and Aghajanian, 1978; Deniau et al., 1978; Tepper et al., 1982). Under these conditions, the neurons exhibit 3 distinct patterns or modes of firing.
