Afferent nerve fibres cross the midline from the cochlear nucleus to the cell bodies of the MOCS ( located near the MSOC ), whose efferent fibres project back to the cochlea ( red ).
32.
However, it is not clear whether these afferent nerves are modulated during normal day-to-day activities of living and, if so, what segmental or whole-body reflex effects they may have ."
33.
Whenever these afferent nerve endings are stimulated ( for example, by dust, cold air or fumes ) impulses travel to the brain-stem vagal center, then down the vagal efferent pathway to again reach the bronchial small airways.

The mechanism of referred pain has been elucidated clearly in many textbooks of Physiology : At the same segment of the spinal cord, the cardiac afferent nerve afferent nerve converges with the cutaneous afferent from the medial skin of upper limb.

Complementing this, afferent nerve fibres have been found that project to early visual areas such as the lingual gyrus from late in the dorsal ( action ) and ventral ( perception ) visual streams, as well as from the auditory association cortex.
37.
One research group has reported that TRPM8 is activated by chemical cooling agents ( such as menthol ) or when ambient temperatures drop below approximately 26 �C, suggesting that it mediates the detection of cold thermal stimuli by primary afferent sensory neurons of afferent nerve fibers.
38.
In mammals, electrical recordings from single afferent nerve fibres have shown that the responses of Merkel nerve endings are characterized by a vigorous response to the onset of a mechanical ramp stimulus ( dynamic ), and then continued firing during the plateau phase ( static ).
39.
An " afferent nerve " is a sensory nerve that conveys impulses from the skin and other sensory organs to the spine and the brain . " Deafferentation " is a surgical procedure in which the spinal cord is opened up and the sensory nerves cut so that these impulses do not reach the brain.
40.
Data source : Information was obtained from chiropractic or, scientific peer-reviewed literature concerning human or animal studies of neural responses to vertebral subluxation, vertebral displacement or movement, or both . " He concluded, " Animal models suggest that vertebral displacements and putative vertebral subluxations may modulate activity in group I to IV afferent nerves.
