Comparing tactile pattern and vibrotactile frequency discrimination: a human FMRI study.
We investigated to which extent the discrimination of tactile patterns and vibrotactile frequencies share common cortical areas. An adaptation paradigm has been used to identify cortical areas specific for processing particular features of tactile stimuli. Healthy right-handed subjects performed a delayed-match-to-sample (DMTS) task discriminating between pairs of tactile patterns or vibrotacti...
متن کاملSupracutaneous vibrotactile perception threshold at various non-glabrous body loci.
Researchers at the University of Nebraska-Lincoln are currently designing a wearable/portable neutron detector. As an alerting mechanism, the device will transmit vibration to the wearer's skin in the presence of hazardous levels of neutron radiation. The present study was designed to help in the ergonomically correct body placement of the neutron detection device while providing numerical valu...
متن کاملVibrotactile frequency discrimination in human hairy skin.
The human capacity for vibrotactile frequency discrimination has been compared directly for glabrous and hairy skin regions by means of a two-alternative, forced-choice psychophysical procedure in five subjects. Sinusoidal vibratory stimuli, delivered by means of a 4-mm-diam probe, were first used to obtain detection threshold values for the two skin sites, the finger tip and the dorsal forearm...
متن کاملHaptic curvature discrimination at several regions of the hand.
Static haptic discrimination of the curvature of convex, concave, or straight 20-cm-long strips was investigated for nine placements on the hand. In one condition, the strips were touched with the palmar side of the hand, and in the other condition, with the dorsal side. The influence of the lengths of the strips, and thus of contact lengths, was also investigated. For all placements, discrimin...
متن کاملVibrotactile Discrimination of Pure and Complex Wave- forms
Here we present experimental results that investigate the application of vibrotactile stimulus of pure and complex waveforms. Our experiment measured a subject’s ability to discriminate between pure and complex waveforms based upon vibrotactile stimulus alone. Subjective same/different awareness was captured for paired combinations of sine, saw, and square waveforms at a fixed fundamental frequ...
