Galvanic Vestibular Stimulation influences risk-taking behaviour

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. Left-anodal right-cathodal GVS (L-GVS), which preferentially activates projections in right hemisphere, decreased willingness take risk during BART compared right-anodal left-cathodal (R-GVS), left hemisphere. This proved specific effect depends on polarity. Conversely, no generic effect, defined as adjusted average L-GVS R-GVS conditions sham, emerged, excluding Our results confirmed recent findings contribution decision-making strategy behaviour. suggest that vestibular-mediated balancing seeking important element brain's capacity adapt
