Podcast on the brain and navigation

Being a navigationally-challenged blind woman, I found this episode of RadioLand titled "Lost and Found" particularly fascinating. One of the things which I find curious about sighted people is how often they reduce navigation to a visual experience, when what is going on is really a multi-modal process, and this episode does a great job of explaining about that. Also, the segment with Charlie the Pigeon Man of Cornell is absolutely great, not only because how pigeons find their way home is really cool but because scientists are still compelled to admit f*** if they know how the birdbrains do it. Finally, the last segment is just a total tearjerker, because there can never be too many true stories about a blind woman and the guy with the not-so-secret-fuzzy-heart who loves her
