This study was sponsored by the University of Wisconsin–Madison Industrial & Economic Development Grant , Investigation of brain plasticity in electrotactile vestibular sensory substitution. The project period was 7/1/2007–6/30/2008. The principal investigator was Mitchell Tyler and was conducted in collaboration with Professor Beth Meyerand, UW Department of Medical Physics.
This project examines brain activity responsible for recovery of balance, posture, and gait in vestibular-impaired persons, while using a system that delivers a sensory substitution and neuromodulation stimulus to the brain through the tongue. Brain activity is measured using Functional Magnetic Resonance Imaging (fMRI). We are interested in finding out which areas of the brain are responsible for the long-term restoration of balance function using balance sensory substitution via the tongue.
