“…To support his contention, Verrillo compared vibratory sensory data obtained from the palmar surface to data obtained from the dorsal lingual surface. His results directly conflicted with those obtained by Sherrick (1953). Verrillo (1966) reported a flat frequency curve for the lingual surface and a U-shaped curve for the palmar surface.…”

“…Sherrick (1953) reported that the dorsal lingual surface was selectively responsive to test frequencies from 40 to 1,200 Hz, with maximum sensitivity being demonstrated at approximately 200-250 Hz. These results conformed to previous data from nonoral structures (Sherrick, 1953). Verrillo (1966) questioned the fmdings of Sherrick on the basis that the dorsal lingual surface is void of the type of sensory receptors necessary for a frequency-selective response to vibratory stimuli.…”

A handle with strain gauges attached ·was used to study the effect of compression force (10, 20 and 40 N) and constant acceleration (1, 3 and 10 g) on the transmission of vibration at frequencies from 20 to 630 Hz. In the curves recorded, sharp dips appeared which were evidently caused by resonances from the soft tissues of the hand. However in the hand-arm system no common resonance frequency was observed that would harmfully affect the health of workers. Vibration in the hand-arm system was attenuated at an average of 3 dB per octave at the frequencies between 20 and 100 Hz. Between 100 and 630 Hz the attenuation was about 6 dB per octave in the wrist and 10 dB per octave in the elbow and upper arm. At the frequency of 630 Hz the attenuation was hence about 35 dB in the wrist and about 45 dB in the elbow. The attenuation of vibration in the elbow joint was 2 to 4 dB at all frequencies. The hand-arm system appears to be linear at the acceleration range considered; the increase)n handle vibration by, e.g., 10 dB also increased vibration in the hand by 10 dB. When the grip strength was increased fourfold, Le., 12 dB, vibration increased only 3 to 5 dB in the hand-arm system. Thus changing the weight of a vibrating tool does not reduce vibration enough. Therefore attempts to reduce Vibration should concentrate on the mechanical parts of the engines.

“…Verrillo (1966Verrillo ( , 1968 found that when a vibrotactile stimulus was presented through a rigid surround (with a l-mm gap), sensitivity on the dorsal surface was independent of the frequency of vibration. The flat frequency function Verrillo obtained with a surround was in sharp contrast to the If-shaped function that was typically obtained on the dorsum of the tongue when no surround was present (Sherrick, 1953;Verrillo, 1966). Verrillo reasoned that the surround prevented vibration delievered to the dorsal surface from reaching Pacinian corpuscles (Pes), which anatomical evidence had indicated lay in the dermis beneath the ventral surface of the tongue.…”

Two experiments were carried out to investigate the effect of cooling on the sensitivity of the tongue to vibration. In the first experiment the temperature of the tongue was held at 36 0 , 28 0 , or 20 0 C while the thresholds for detecting 30-and 250-Hz vibrations were measured using a twoalternative forced-choice paradigm. Cooling the tongue to 20 0 reduced the sensitivity to 250-Hz vibration but did not disturb the sensitivity to 30-Hz vibration. The second experiment established that cooling continued to reduce the sensitivity to the 250-Hz stimulus even when intensity levels were raised to 30 dB SL. The results are discussed in relation to (1) which types of mechanoreceptors mediate the perception of vibration on the dorsal surface of the tongue, (2) the effect of a rigid surround on lingual vibrotactile sensitivity, and (3)the possible impact of temperature on perception of the mechanical characteristics of foods.Tactile information from the tongue is important for both the manipulation and the sensory assessment of ingested foods. In recognition of this fact and because of the presumed importance of tactile feedback from the tongue during speech production, a relatively large literature has developed on lingual mechanical sensitivity.
