Peripheral galvanic vestibular stimulation (GVS) has been shown to temporarily ameliorate left spatial neglect [1]. Specifically, anodal (facilitatory) stimulation over the left mastoid bone coupled with cathodal (inhibitory) over the right mastoid reduces visuospatial‐neglect scores in line cancellation [2] and line bisection tasks [3, 4]. This montage increases activity in the left vestibular...

in an attempt to diminish the intensity of vertigo, this study was designed to reduce the imbalance between the vestibular system on the two sides. by rotating the subjects with a string-activated rotating chair in opposite direction of the dominant side, the dominant side would be inhibited and simultaneously the subordinate ide would be stimulated. eight patients with vestibular vertigo confi...

This paper describes two aspects of the application of tactile information presentation in the cockpit. The first half of the paper discusses why the tactile channel might be used instead of, or in addition to, the more common visual and auditory channels. It lists several categories of information used in cockpits and explores their appropriateness for tactile stimulation. The second half of t...

We studied on the feasibility of focused ultrasound for tactile feeling display. Our experiments showed that focused ultrasound at 1 MHz and 5 MHz effected our somatic sensation both by its radiation pressure and by direct stimulation to the nerve structures. The radiation pressure force generated by our apparatus was 0.23 gf/cm per 1-watt power consumption and evoked tactile feeling stably, wh...

BACKGROUND AND PURPOSE Deep brain stimulation (DBS) of the pedunculopontine nucleus (PPN) reduces the number of falls in patients with Parkinson's disease (PD). It was hypothesized that enhanced sensory processing contributes to this PPN-mediated gait improvement. METHODS Four PD patients (and eight matched controls) with implanted bilateral PPN and subthalamic nucleus DBS electrodes were ass...

Optic flow patterns generated by self-motion relative to the stationary environment result in congruent visual-vestibular self-motion signals. Incongruent signals can arise due to object motion, vestibular dysfunction, or artificial stimulation, which are less common. Hence, we are predominantly exposed to congruent rather than incongruent visual-vestibular stimulation. If the brain takes advan...

Two crucial sources of information available to an organism when moving through an environment are visual and vestibular stimuli. Macaque cortical area MSTd processes visual motion, including cues to self-motion arising from optic flow and also receives information about self-motion from the vestibular system. In humans, whether human MST (hMST) receives vestibular afferents is unknown. We have...

Repetitive transcranial magnetic stimulation (rTMS) is an effective tool for inducing functional plastic changes in the brain. rTMS can also potentiate the effects of other interventions such as tactile coactivation, a form of repetitive stimulation, when both are applied simultaneously. In this study, we investigated the interaction of these techniques in affecting tactile acuity and cortical ...
