Functional Near-Infrared Spectroscopy (fNRIS) + Noisy Galvanic Vestibular Stimulation (nGVS)


In this project, we monitor the cortical effects of noisy galvanic vestibular stimulation (nGVS) by measuring the brain activity of participants using a functional near-infrared spectroscopy (fNRIS) device.

nGVS is a non-invasive electrical stimulation technique in which a noise signal is delivered through the mastoids. In the biomedical engineering literature, nGVS has been shown to have beneficial motor effects in different activities, such as standing balance and walking performance in people with and without bilateral peripheral vestibular dysfunction and upper-limb fine motor performance in people with and without Parkinson’s disease.
