Functional MRI of working memory and selective attention in vibrotactile frequency discrimination

BMC Neuroscience, 2007
Background Focal lesions of the frontal, parietal and temporal lobe may interfere with tactile working memory and attention. To characterise the neural correlates of intact vibrotactile working memory and attention, functional MRI was conducted in 12 ...

Vibrotactile signals can aid recognition of spectrally degraded speech signals [PDF]

JASA Express Letters
The potential utility of providing low-frequency portions of speech signals through vibrotactile stimulation as an aid to speech recognition by cochlear implant recipients was examined. Sixty-five young adults with normal hearing heard four-channel noise-

Oscillatory Correlates of Vibrotactile Frequency Processing in Human Working Memory [PDF]

The Journal of Neuroscience, 2010
Previous animal research has revealed neuronal activity underlying short-term retention of vibrotactile stimuli, providing evidence for a parametric representation of stimulus frequency in primate tactile working memory (Romo et al., 1999). Here, we investigated the neural correlates of vibrotactile frequency processing in human working memory, using ...

Feeling voices. [PDF]

PLoS ONE, 2013
Two experiments investigated deaf individuals' ability to discriminate between same-sex talkers based on vibrotactile stimulation alone. Nineteen participants made same/different judgments on pairs of utterances presented to the lower back through voice ...

Enhanced Design of a Soft Thin-Film Vibrotactile Actuator Based on PVC Gel

Applied Sciences, 2017
We fabricated a soft thin-film vibrotactile actuator, which can be easily inserted into wearable devices, based on an electroactive PVC gel. One of the most important factors in fabricating a soft and thin vibrotactile actuator is to create vibrational ...
