The relation of vibratory sensitivity to pressure.

Normative Study of Oral Vibrotactile Sensitivity

“…I t strongly supported the contention that vibratory sensations were mediated by the same peripheral mechanisms that registered sensation to pressure (Curnrnings, 1938;Geldard, 1940a;Gilmer, 1937;Gilmer & Haythorne, 1941;Weitz, 1939). I t strongly supported the contention that vibratory sensations were mediated by the same peripheral mechanisms that registered sensation to pressure (Curnrnings, 1938;Geldard, 1940a;Gilmer, 1937;Gilmer & Haythorne, 1941;Weitz, 1939).…”

The effect of local anesthesia on tactile and vibratory thresholds.

“…He claimed that only the pressure spots gave a characteristic intermittent sensation. Pain and temperature spots gave a continuous sensation with a prickling or thermal component, von Frey's general conclusion has recently been confirmed by Geldard (15) and Gilmer (17). These latter investigators report that with very light punctiform stimulation there is a marked difference in the vibratory sensitivity of 'pressure sensitive' and 'pressure insensitive' spots.…”

Effect of tongue temperature on oral tactile sensitivity and viscosity discrimination

“…Apart from surface temperature, two aspects are influencing vibratory perception thresholds of a particular body site. One point is concerned with intrinsic features of vibratory stimuli, including vibratory frequency, duration, pressure, and contactor surface area as well as contactor configuration (Bikah, Hallbeck, & Flowers, 2006;Fucci & Petrosino, 1982;Gilmer, 1937;Gregg, 1951;Harris, Fucci, & Petrosino, 1988;Verrillo, 1963Verrillo, , 1992. Another aspect associated with vibratory perception depends on factors like age, gender, and BMI (Calhoun, Gibson, Hartley, Minton, & Hokanson, 1992;Verrillo, 1977; R. T. Ronald T. Verrillo, 1979;Verrillo, 1980;Wiles, Pearce, Rice, & Mitchell, 1991).…”
