The Prairie Pooch Hole
Poocher is amazed! A blind man can navigate a maze unaided in any way. He also can detect facial expressions!! Jumping Jack Flash!!!With a study of a blind man who successfully nagivated an obstacle maze unaided, scientists have shown for the first time that it is possible for people who have been left blind after severe brain damage to the visual (striate) cortex to be able to use an ability called "blindsight", where they can detect things in their vicinity without being aware of seeing them.
For the study, de Gelder and colleagues made an obstacle course of randomly arranged boxes, chairs and other objects and invited TN to cross it without help and without using his cane.
The scientists were astonished when TN succeeded in navigating the obstacle course perfectly without help and without his stick. He didn't collide with any of the obstacles and received a resounding and spontaneous round of applause from onlookers when he reached the finish.
He is also able to sense and respond to a variety of facial expressions in other people. When they watched his brain patterns responding to these expressions the researchers found they were consistent with known patterns for emotions like anger, fear and joy.
