The phrase "alterations in the threshold" is correct and usable in written English.
It can be used in contexts discussing changes or modifications to a specific limit or boundary, often in scientific or technical discussions.
Example: "The study revealed significant alterations in the threshold for pain sensitivity among the participants after the treatment."
Alternatives: "changes in the limit" or "modifications to the boundary".
As noted above, the mechanism whereby rizatriptan reduces motion sickness may be related to an alteration in the threshold for motion sickness based on serotonergic mechanisms.
Researches and current models are based on the assumption that it is caused by alterations in the nociceptive threshold and central sensitisation in susceptible individuals [13, 14].
In the present study Tibial and sural nerve transection-induced alterations in the nociceptive threshold, are consistent with the earlier reports [ 21, 31].
Although a change in the threshold would lead to quantitative alterations in the graph theoretical measures, the specific threshold choice (within reasonable limits) does not strongly affect the general qualitative results that we obtained.
We never observed in parallel with the H-reflex alterations significant changes in the threshold and amplitude of the M-wave, nor was the decay phase of the H-reflex (which mainly depends on the increasing number of antidromically activated motor fibres) significantly altered in the patient populations compared with controls.
P = primary tumor; M = metastasis; chr= chromosome; Alterations written within parenthesis represent borderline alterations at the threshold.
Diabetic patients without retinopathy or with minor retinovascular changes have alterations in FDT threshold test with a diminution of the sensitivity.
Alterations in the electrophysiological properties of Aβ-fibre low-threshold mechanoreceptors have been reported in a surgically induced model of OA [ 47].
While it is apparent that the mitochondrial depolarization observed in the HFD group cannot be directly linked to a defect in cytochrome c oxidase, it is possible that alterations in mitochondrial thresholds of respiratory chain enzymes occurred in response to the metabolic stress induced by chronic exposure to a HFD.
While alterations in threshold can be produced by changes in peak conductances of ion channels, they have also been described experimentally by heating in invertebrate systems (Burkhardt, 1959; Abrams and Pearson, 1982; Kispersky et al., 2012) in agreement with our observations.
