Neurobehavioral Effects of Visual Assistive Technology

Brief description of study

This research uses magnetic resonance imaging (MRI) to study changes in brain activity for subjects that are being trained to use sensory substitution devices. Advanced MRI techniques are currently used to study the brain structure and function both in healthy individuals and in patients with a variety of diseases and conditions. Our aim is to measure the responses induced in vision areas of the brain in blind subjects that use these sensory substitution devices as a means to “see” through their tactile perception on the body or auditory perception via headphones. Subject brains will be scanned with a FDA-approved 3-Tesla MRI system, commonly used for this type of research.
