“…Yamashita, & Sato, 1964;Poulos & Benjamin, 1968;Poulos & Lende, 1970). The chorda tympani nerve, which is the primary nerve for taste, contains most of the few oral warm fibers reported in nonprimates (Dodt & Zotterman, 1952;Sato, 1967). Unfortunately, there appear to have been no electrophysiological studies of the thermal components of the mental branch of the mandibular nerve, which innervates the inferior labial mucosa.…”

“…It should be emphasized, however, that the mucosal lip in particular appears to be poorly innervated by both populations of afferents. Evidence for poor oral innervation by the warmth sense abounds in the sensory physiology literature: The preponderance of thermally responsive afferents in the lingual nerve and the thermally responsive cells in the thalamus respond to cooling but not to warming (Dodt & Zotterman, 1952;Iriuchijima & Zotterman, 1960;Nagaki, . Yamashita, & Sato, 1964;Poulos & Benjamin, 1968;Poulos & Lende, 1970).…”

The perception of warmth and cold was measured on six labial and lingual loci plus the fingertip. The results indicate that (1) the responsiveness to warming varies substantially across oral sites; (2) compared to warming, the responsiveness to cooling is more homogeneous across oral locations and somewhat stronger relative to the fingertip; (3) the psychophysical function for warmth on the vermilion lip and the labial mucosa has two limbs that may represent the contributions of two sensory systems to perceptions of warmth; and (4) the psychophysical functions on labial skin tend to be accelerated for warmth and decelerated (compressed) for cold. The differences in responsiveness within and between thermal modalities are considered in terms ofprobable differences in both neural innervation and the physical properties of the skin. It is hypothesized that the oral contribution to thermoregulation, although arguably minor, may be greater for cold than for warmth.

“…In the earlier study, dynamic contact suppressed cold sensations under conditions in which warm fibers would be simultaneously inhibited by cooling. In the present study cold sensations were suppressed when skin temperature remained constant at approximately 33°C, a temperature at which warm fibers continue to discharge statically [50][51][52]. It is possible the static activity in warm fibers was adequate to induce warmth after the corresponding static activity in the cold pathway had been inhibited.…”

It was recently found that cooling the skin to temperatures as mild as 25°-30°C can induce nociceptive sensations (burning, stinging or pricking) that are strongly suppressed by dynamic contact between the thermode and skin (contact suppression). Here we investigated whether nociceptive sensations produced by menthol can be similarly suppressed. In the first experiment subjects rated the intensity of cold and burning/stinging/pricking sensations before and after application of 10% l-menthol to the forearm. Ratings were compared at resting skin temperature (≈ 33°C) and at 28°, 24°, or 20°C during static or dynamic contact cooling via a Peltier thermode. At resting skin temperature, menthol produced cold and nociceptive sensations, both of which were suppressed by dynamic contact. When the skin was cooled during static contact, menthol increased nociceptive sensations but not cold sensations; when the skin was cooled during dynamic contact, cold sensations were again unchanged while nociceptive sensations were suppressed. A second experiment tested whether contact suppression of menthol's cold and nociceptive sensations at resting skin temperature was caused by slight deviations of thermode temperature above skin temperature. The results showed that suppression occurred even when the thermode was slightly cooler (−0.5°C) than the skin. These findings support other evidence that the menthol-sensitive channel, TRPM8, plays a role in cold nociception, and raise new questions about how dynamic tactile stimulation may modify perception of nonpainful cold stimulation.
