Afferent pain pathways: a neuroanatomical review
Brain Research, 2004Painful experience is a complex entity made up of sensory, affective, motivational and cognitive dimensions. The neural mechanisms involved in pain perception acts in a serial and a parallel way, discriminating and locating the original stimulus and also integrating the affective feeling, involved in a special situation, with previous memories.

Serotonergic modulation of bladder afferent pathways
Urology, 2003Normal bladder function is based on activation and maintenance of a sophisticated reflex mechanism involving sympathetic, parasympathetic, and somatic control of the lower urinary tract. The spinal and supraspinal neuronal pathways involved can be modulated by activation or inhibition of neurons in the periphery, at the lumbosacral and thoracolumbar ...

Afferent Pathways of Pyrogen Signalinga
Annals of the New York Academy of Sciences, 1998ABSTRACT: We and others recently showed that fever induced by intravenously or intraperitoneally injected lipopolysaccharide (LPS) may involve brain signaling via hepatic vagal afferents. This suggests that LPS fever may be initiated by mediators released mainly by cells in the liver, presumably macrophages (Kupffer cells, Kc).

Central Organization of Afferent Renal Nerve Pathways
Clinical and Experimental Hypertension. Part A: Theory and Practice, 1987Although afferent renal nerves have been studied for over a quarter of a century, their physiological role remains unclear. There is considerable experimental evidence indicating that afferent renal nerves convey sensory information from renal receptors to integrative circuits in the central nervous system which gives rise to command signals ...

Neuropeptides in pelvic afferent pathways
Experientia, 1987Neurochemical and pharmacological experiments have raised the possibility that several neuropeptides including, vasoactive intestinal polypeptide (VIP), peptide histidine isoleucine amide (PHI), substance P, calcitonin gene-related peptide (CGRP), neurokinin A, cholecystokinin (CCK) and opioid peptides may be transmitters in afferent pathways to the ...

Afferent respiratory pathways in the avian vagus
Experientia, 1968Nous avons enregistre 88 afferences respiratoires du nerf vague chez le poulet. Quelques unes se declenchaient au cours de l'inspiration eupneique, d'autres au cours de l'expiration. Jusqu'a present, on a l'impression qu'il existe plus de types d'activite afferente respiratoire chez l'oiseau que chez le mammifere, mais de nouvelles analyses seront ...

Afferent nerve groups and sympathetic reflex pathways
Brain Research, 1969Summary In chloralose-anesthetized cats, two reflex sympathetic discharges were recorded from lumbar white rami after single shock stimulation of peripheral afferent nerves: an early discharge associated with a spinal reflex pathway, and a late discharge associated with a supraspinal pathway.

Sensory processing in a thermal afferent pathway
Journal of Neurophysiology, 1985Extracellular recordings were made from cold-receptive afferent fibers in the trigeminal ganglion of rats anesthetized with halothane. By applying a standardized series of steady or changing temperatures to the receptive fields, we recorded the static and dynamic responses of the afferents.

Chronic cough: ATP, afferent pathways and hypersensitivity
European Respiratory Journal, 2019New evidence from tussive challenges and the P2X inhibitor gefapixant strengthens ATP as a driver of chronic cough. Cough responses to other irritants probably involve a separate peripheral activation pathway.

Fiber Size and Organization of Afferent Pathways
Archives of Neurology, 1961Concepts of the organization and functional characteristics of afferent pathways in the central nervous system have been derived from anatomical studies of large fiber myelin sheath degeneration by the Marchi method; observation of centrally recorded, electronically amplified potentials resulting from peripheral nerve stimulation; and clinical ...
