Blind Use Echolocators and Access the Visual Cortex

"Canadian expert Mel Goodale determines echolocators use echoes to detect multiple properties of objects through areas of the brain associated with vision," writes Medical News Today. "Certain blind individuals have the ability to use echoes from tongue or finger clicks to recognize objects in the distance, and some use echolocation as a replacement for vision. Research done by Dr. Mel Goodale, from the University of Western Ontario, in Canada, and colleagues around the world, is showing that echolocation in blind individuals is a full form of sensory substitution, and that blind echolocation experts recruit regions of the brain normally associated with visual perception when making echo-based assessments of objects. Dr. Goodale's latest results were presented at the 9th Annual Canadian Neuroscience Meeting in Vancouver British Columbia." Read more.
