Risk-taking behaviour is an essential aspect of our interactions with the environment. Here we investigated whether vestibular inputs influence behavioural measurement risk-taking propensity. We have combined bipolar Galvanic Vestibular Stimulation (GVS) a well-known and established task, namely Balloon Analogue Risk Task (BART). A sham stimulation was used to control for non-specific effects. ...

The purpose of this study was to evaluate the effect of galvanic vestibular stimulation (GVS) on recovery from gaze palsy. Twenty patients with gaze palsy, (14 males and 6 females) their age ranged from 20–63 years with mean age 47.9±12.5 years. Duration of gaze palsy ranged from 4–24 months with mean of 10.6±5.23. Twelve patients were post stroke and eight patients with definite multiple scler...

Balance requires the integration of proprioceptive, visual, and vestibular sensory inputs. Contributions from the vestibular system are increasingly important when other sensory signals are lacking or erroneous [1]. Galvanic vestibular stimulation (GVS), the application of a small electrical current across the mastoid processes, has been used to apply a stimulus to the vestibular system indepen...

Luigi Galvani spent 20 years conducting experiments to demonstrate electrical conductivity of nerves and muscles before publishing his major treatise on the subject in 1791 (Galvani, 1791). His personal friend and professional nemesis Count Alessandro Volta held a respectful but opposing view, that nerve and muscle tissues simply serve as passive conductors, and he built the first “voltaic” bat...

The cortical processing of vestibular information is not hierarchically organized as the processing of signals in the visual and auditory modalities. Anatomic and electrophysiological studies in the monkey revealed the existence of multiple interconnected areas in which vestibular signals converge with visual and/or somatosensory inputs. Although recent functional imaging studies using caloric ...

Hemi-spatial neglect is an attentional disorder in which the sufferer fails to acknowledge or respond to stimuli appearing in contralesional space. In recent years, it has become clear that a measurable reduction in contralesional neglect can occur during galvanic vestibular stimulation, a technique by which transmastoid, small amplitude current induces lateral, attentional shifts via asymmetri...

This paper presents the analysis on effects of GVS(Galvanic Vestibular Stimulation) to mastoid process on postural balance and stability using 3 dimensional motion analysis. The experiments were performed by providing the experimental subjects a bipolar binaural galvanic vestibular stimulation during standing and walking, and then the postural stability was evaluated by 3 dimensional motion ana...
