Journal ArticleDOI
Spatial and temporal codes mediate the tactile perception of natural textures
Alison I. Weber,Hannes P. Saal,Justin D. Lieber,Ju-Wen Cheng,Louise R. Manfredi,John F. Dammann,Sliman J. Bensmaia +6 more
TL;DR: In this paper, a combination of spatial and temporal mechanisms, mediated by all three populations of afferents, accounts for perceptual judgments of texture in Rhesus macaques using a custom-made rotating drum stimulator.
Journal ArticleDOI
Touch is a team effort: interplay of submodalities in cutaneous sensibility.
TL;DR: It is argued that cortical neurons should be grouped based on their function rather than on their submodality composition, as most natural stimuli excite all afferents and most tactile percepts are shaped by multiple submodalities.
Journal ArticleDOI
The neural basis of perceived intensity in natural and artificial touch
Emily L. Graczyk,Matthew A. Schiefer,Hannes P. Saal,Benoit P. Delhaye,Sliman J. Bensmaia,Dustin J. Tyler,Dustin J. Tyler +6 more
TL;DR: These findings support the hypothesis that population spike count drives the magnitude of tactile percepts and indicate that sensory magnitude can be manipulated systematically by varying a single stimulation quantity.
Journal ArticleDOI
Simulating tactile signals from the whole hand with millisecond precision.
TL;DR: A model to simulate the responses of all tactile fibers innervating the glabrous skin of the hand to any spatiotemporal stimulus applied to the skin is developed and it is shown that simulated fibers match biological ones across a wide range of conditions sampled from the literature.
Journal ArticleDOI
Natural scenes in tactile texture
Louise R. Manfredi,Hannes P. Saal,Kyler J. Brown,Mark C. Zielinski,John F. Dammann,Vicky S. Polashock,Sliman J. Bensmaia +6 more
TL;DR: It is concluded that it is impossible to understand the neural basis of texture perception without first characterizing the skin vibrations that drive neural responses, given the complex dependence of skin vibrations on both surface microgeometry and fingertip biomechanics.
