Second, via innate aversion, conditioning, or stress responses, odorant compounds can induce symptoms such as nausea, vomiting, headaches, stress, negative mood, and a stinging sensation at concentrations higher than the olfactory nerve threshold but below the trigeminal nerve threshold (Schiffman 1998; Schiffman et al. 2000; Shusterman 1992, 2001; Shusterman et al. 1991).
While the mechanism/s of chronic idiopathic cough are currently unknown it has been proposed that chronic idiopathic cough maybe similar to other sensory hyperalgesias, where there is a long-standing reduction in sensory nerve threshold to stimulation [ 29, 30].
This subsequently contributes to reductions in nerve thresholds at nociceptive terminals, increases in sensitivity, and amplification of the excitability of the peripheral afferent nerve fibers [32].
There were no significant correlations between esophageal and median nerve thresholds in either group (all P > 0.3).
This subsequently contributes to reductions in nerve thresholds at nociceptive terminals, increases in sensitivity, and amplification of the excitability of the peripheral afferent nerve fibers [ 32].
This multiple excitability protocol assesses motor-nerve threshold following different conditioning stimuli [12].
Nevertheless, the trend of the treated group approaching the contralateral healthy nerves threshold is a good evidence of reinnervation.
When an electrode is placed on this nerve, its threshold sensitivity and overall frequency range can be determined by varying the intensity and frequency of the sounds applied to the tympanic membrane.
Sensory nerve conduction threshold was measured in large myelinated, small myelinated, and unmyelinated nerve fibers.

Functionally, it is near the end of the second postnatal week that mice begin responding to sound with more mature auditory nerve activation thresholds [16].
