On experiencing distal-proximal tactile motion on the volar side of the forearm starting at the wrist, subjects significantly anticipate touch of the elbow crook. This illusion, popular as a children's game, was quantified in ninety participants (forty-seven women) on both arms. As a top-down explanation of the illusion, we discuss a model of Bayesian inferences. As a bottom-up contribution, we consider afterdischarges of cortical neurons, which receive input from skin mechanoreceptors…

Tactile Toe Agnosia and Percept of a “Missing Toe” in Healthy Humans

TLDR
These findings challenge current models of somatosensory localization, as they cannot be explained simply by a lack of distinct representations for toes compared with fingers, or by overt toe-finger correspondences.

Implied tactile motion: Localizing dynamic stimulations on the skin

TLDR
An overall pattern of localization shifts analogous to what has been described previously in the visual and auditory modalities is reported, and participants perceive the last location of a dynamic stimulus further along its trajectory than is objectively the case.

Pins & Needles: Towards Limb Disownership in Augmented Reality

TLDR
It is demonstrated that a controlled, visuotactile conflict about one’s own limb can be used to directly and systematically modulate ownership – without a proxy, which corroborates the malleability of body representation but questions its permanence.

A Case of Perceptual Completion in Spatio-Temporal Tactile Space

We reproduced a perceptual phenomenon where a tactile stimulus moving on the fingertip jumps instantly over a gap but is felt as if the space of the gap was perceptually obliterated. This phenomenon

Tactile motion lacks momentum

TLDR
Contrary to the prediction based on the representational momentum literature, participants in this experiment significantly displaced the endpoint against the direction of movement (underestimation), and the results are compatible with previous psychophysical findings on the perception of tactile motion.

The tactile motion aftereffect suggests an intensive code for speed in neurons sensitive to both speed and direction of motion.

TLDR
The strength of the tMAE increased monotonically with adapting speed, regardless of the test speed, showing no evidence of speed tuning, consistent with neurophysiological findings that suggest an intensive code for speed along the motion processing pathways comprising neurons sensitive both to speed and direction of motion.

Laterality in the rubber hand illusion

TLDR
A right-hemispheric dominance for sense of body ownership in healthy adults is suggested by the results of a rubber hand illusion study, which elicits vividness and skin conductance responses to watching the rubber hand being harmed.

Tactile spatial acuity varies with site and axis in the human upper limb

A Bayesian Perceptual Model Replicates the Cutaneous Rabbit and Other Tactile Spatiotemporal Illusions

TLDR
The results suggest that the brain automatically incorporates prior expectation for speed in order to overcome spatial and temporal imprecision inherent in the sensorineural signal.

Tactile and Haptic Illusions

TLDR
This paper surveys the research literature on robust tactile and haptic illusions by briefly considering a number of important general themes that have emerged in the materials surveyed.

Dependence of subjective traverse length on velocity of moving tactile stimuli.

TLDR
It is interesting that the plateau of the relationship between perceived stimulus distance and velocity occurred within therange of velocities that human subjects employ to scan textured surfaces; it also corresponded precisely with the range of stimulus velocITIES at which the directional sensitivity of somatosensory cortical neurons and human subjects is optimal.
