“…Clark (1969), Dillon (1971), Fujita (1930), and Lele, Weddell, and Williams (1954) showed that radiant thermal stimulation to the skin produces the sensations of warmth, sting, pain, itch, and occasionally faint touch, depending on the intensity and duration of heat transfer. A similar transition of sensory qualities was found by Guilford and Lovewell (1936) and Yai (1959Yai ( , 1961 for mechanical stimulation of the skin. Therefore, the method of modality intersection appears to be a very promising technique for analyzing the intensityduration relation of these cutaneous qualities.…”

A preliminary and two main experiments designed to examine the perceptual properties of electrocutaneous stimulation are reported. The stimuli used were single short pulses varying in intensity and duration. In Experiment 1, the exponents of power functions fitted to electrocutaneous magnitude estimation data were determined together with the sensory qualities induced by electrical stimulation. The results showed that there was no correlation between the exponent values and the sensory qualities. The mean exponent was 1.2. In Experiment 2, an intensity-duration trading function was constructed from the data obtained from identifying the induced sensory qualities. The results showed that the critical duration increases from 30 to 300 msec with increasing sensation level. These findings are compared with the properties of other sense modalities.

“…Previously Obonai proposed " measurement of pressure spot density " which used the number of pressure spots in a given area as an indicator of pressure sensitivity (Yai, 1959). Pressure sensitivity is ordinarily indicated by a mean threshold of pressure spots in a given area (limezu & Kuroki, 1953).…”

“…Thus the effect of the stimulation will be maximal in periphery of the area, accounting for the apparent brightness of the edges. Moreover, since the inhibition in the surround is maximal around the edges, the resulting contrast will be enhanced ever further at this point, contributing to the apparent brightness of the edges.The possibility of the existence of an analogous situation of spatial interaction of inhibition and excitation on the receptor level of the somatosensory system had been suggested by Yai (1959) and von Bekesy (1959). Bekesy (1960) elaborated the problem by postulating from psychophysical experiments a neural funneling unit model common to the eye and the skin senses which could explain spatial contrast phenomena.…”

The nature of the adequate stimulus for tactile sensitivity remains a controversial issue. Several theories have been proposed to define the stimulus, the earliest one probably being that of Meissner (1859), who suggested that tactile sensitivity depends on the contrast between stimulated and adjacent unstimulated area, and not on the stimulus per se, While Meissner derived his theory from introspective analysis, von Frey and Kiesow (1899), who used absolute threshold measurements, concluded that tension is the basic determinant of the sensitivity of the skin to mechanical stimuli. Holway and Crozier (1937) came to a different conclusion through the use of the differential threshold technique, by finding linear relations between pressure (and not tension) and tactile sensitivity. Unfortunately, the use of discrete additions of the stimulus force by von Frey and Kiesow vs a continuous addition of it by the latter authors does not permit a direct comparison of their opposing results. This point was stressed by Jenkins and Stone (1941) and is highlighted by numerous investigations which demonstrated the influence of the rate of application of the stimulus on the threshold (Grindley 1934 a,b; Wolf, 1937) and by the psychophysical and physiological experiments of Nafe and Wagoner (1941) and Nafe and Kenshalo (1958) who found pressure perception and cutaneous nerve activity only during progressive mechanical deformation.In spite of the fact that the three above-mentioned theories differ, they have in common an attempt to correlate the areal distribution of the mechanical stimulus with its perception. These theories were formulated on the basis of psychophysical observations alone without consideration of the neurophysiological events in the receptors. Recently an attempt has been made by Ratliff and Hartline (1959) to investigate the effect of concomitant stimulation of several receptor units on the areal distribution of the intensity of the local response. In a set of experiments done on the compound eye of the Limulus they have found that neighboring receptors exert inhibition on each other. This inhibition is an inverse function of the distance between the receptors and a direct function of the intensity of the stimulation applied to the inhibiting receptor. Ratliff and Hartline inferred that a similar state of affairs holds for a sensory organ endowed with more complex connections between the receptors, such as the vertebrate eye. For example, if a limited area of the eye is under uniform illumination, the amount of excitation in this area will not be uniform. The inner receptors in the area will be subjected to more inhibition than the peripheral ones due to the geometrical arrangement. Thus the effect of the stimulation will be maximal in periphery of the area, accounting for the apparent brightness of the edges. Moreover, since the inhibition in the surround is maximal around the edges, the resulting contrast will be enhanced ever further at this point, contributing to the apparent brightness of the edge...
