Pain-related electrical potentials of the human nasal mucosa elicited by chemical stimulation
Abstract
For the first time a non-invasive method was employed to record pain-related electrical potentials from the human respiratory nasal mucosa. Gaseous stimulants at painful concentrations were presented by the newly developed stimulating device. The amplitudes of the potentials were found correlated (a) with concentrations of the stimulants, and (b) with subjective estimations of pain intensity. The local anesthetic tetracaine hydrochloride, and also a systemically administered analgesic drug pentazocine given prior to painful stimulation decreased the amplitude of the negative potentials. The peripheral response was interpreted as a summated receptor potential from chemical nociceptors. It is thought to be analogous to the electro-olfactogram. This non-invasive technique of stimulation and recording offers an objective and quantitative measure related to pain sensations and their inhibition by analgesic drugs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
