“…In man, foci of minimal threshold for vibration sensibility and points of sensitivity to pressure are said to coincide on the skin (Geldard, 1940). This could not be readily explained by assuming the Pacinian corpuscle is the responsible receptor.…”

“…The sensitivity of many of these corpuscles is so great that very small vibrations transmitted through the skin and soft tissues readily evoke discharge. Pacinian corpuscles have also been found adjacent to tendons (Adrian & Umrath, 1929;Gray & Matthews, 1951 a), near joints (Skoglund, 1956), and in muscle (Hinsey, 1934 The literature on vibration sensation in man is extensive and confficting (for a review see Geldard, 1940) and cannot be considered in detail here. From the standpoint of possible receptor mechanism, the data from the cat suggest the Pacinian corpuscle as the most probable receptor, certainly if one considers frequencies in excess of 200 c/s.…”

“…This corresponds to the upper limit of the frequency range of Pacinian corpuscles. However, others have placed the upper limit of vibration sensibility in man at 10,000 c/s or more (Geldard, 1940).…”

Hunt & McIntyre (1960) recently investigated the conduction velocity and receptor characteristics of afferent fibres in the nerves to flexor longus digitorum (FLD) and to the associated interosseous region of the cat. A considerable number of fibres in this interosseous nerve showed discharge to vibratory stimuli applied to the tibia or fibula. The receptors of many such fibres were extremely sensitive, responding to remotely induced vibration such as that produced by slight jarring of the floor or by light stroking of the skin of the lower limb.The present report concerns a study of the type of receptor related to the fibres showing responses to vibration. The receptors will be shown to be Pacinian corpuscles. A large number of such corpuscles lie, in close association with the periosteum, along the tibia, near the interosseous membrane. Evidence will be presented suggesting that Pacinian corpuscles are concerned with vibration sensibility. METHODS Adult cats were anaesthetized with sodium pentobarbital (Nembutal; Abbott Laboratories). The region from popliteal fossa to calcaneus was exposed by a longitudinal incision and the gastrocnemii, soleus and plantaris muscles were removed. The interosseous nerve was identified and traced distally. It courses between the medial and lateral heads of FLD, then through the lateral head of FLD, to run alongside the tibia just dorsal to the interosseous membrane. In order fully to expose the interosseous nerve and the interosseous membrane, the lateral head of FLD was carefully removed. This stage of the dissection was carried out with a stereomicroscope, at a magnification of 7 to 20 times. Exposed tissues were covered by a pool of paraffin oil. Afferent discharge was recorded from Pacinian corpuscles in the following ways: from fibres in the interosseous nerve, from dorsal root filaments containing single fibres from the interosseous nerve, or from nerve fibres from individual corpuscles. In certain experiments afferent discharge was recorded from the sural nerve or the muscle nerve to the medial head of FLD. For recording, fine platinumiridiuim electrodes were used, the potentials being amplified and displayed on a Tektronix 502 oscilloscope. Vibration was provided by an earphone with a glass stylus attached to the diaphragm; this was driven by a sine-wave oscillator of variable frequency and amplitude.

“…However, mechanical vibration (or other dynamic means of stimulating the skin) apparently demonstrate only a slow increase in threshold value when vibratory stimulation is continued for a significant period of time (Geldard, 1940) Also, in displays such as we are considering here, no single stimulator is likely to have a significant proportion of on-time. Adaptation is very unlikely to be a factor of any significance in dynamic tactual displays.…”

“…Geldard (ref 17) supplied an excellent history of the controversy up until 1940 and a rather extensive (214 items) bibliojraphy, Geldard dealt with the various arguments which had been raised in support of a separate vibratory sense and concluded that there was no need for postulation of such a separate sense. He felt that vibration and pressure were different temporal expressions of the same perceptual pattern of feeling.…”
