Purpose: The phenomenon of developing a certain tactile sensibility through osseointegrated dental implants is called osseoperception. Active tactile sensibility can be tested by having the subject bite on test bodies. The aim of the study was to assess the active tactile sensibility of osseointegrated single tooth dental implants according to psychophysical method of constant stimuli. Material...

We propose a tentative tactile perception model called Simple Bundle Model and examine it by a tactile display based on ultrasonic radiation pressure. The ultrasonic tactile display reproduces high-resolution stress patterns with wide bandwidth on the skin. It is a multipurpose device for synthesizing high-fidelity tactile feeling, and useful to clarify the human tactile perception. The prototy...

Hyperacuity is a general aspect of animal perception that exploits spatially overlapping sensory receptive fields to perceive at finer acuity than the sensor resolution. Following a recent demonstration of hyperacuity in robot touch, we present a detailed and systematic analysis of localization acuity for both a biomimetic fingertip and a region of tactile skin. We identify three key factors fo...

OBJECTIVE To determine the relationship between tactile function and upper-limb function in children with unilateral cerebral palsy (CP). DESIGN Cross-sectional study. SETTING Assessments were performed in community or hospital venues or in participants' homes. PARTICIPANTS Recruitment information was sent to 253 possible participants with unilateral CP (aged 8-18 y), and N=52 participate...

While the perception of stickiness serves as one of the fundamental dimensions for tactile sensation, little has been elucidated about the stickiness sensation and its neural correlates. The present study investigated how the human brain responds to perceived tactile sticky stimuli using functional magnetic resonance imaging (fMRI). To evoke tactile perception of stickiness with multiple intens...

The simultaneous perception of multimodal sensory information has a crucial role for effective reactions to the external environment. Voluntary movements are known to occasionally affect simultaneous perception of auditory and tactile stimuli presented to the moving body part. However, little is known about spatial limits on the effect of voluntary movements on simultaneous perception, especial...
